Ubuntu problem with CPAN Perl
Most of us are facing problem when we are trying to install Perl packages from CPAN in Ubuntu
(this arises due to the fact that the installations are missing libraries which in turn required for make and build)
Try these steps and it will resolve the problem
sudo apt-get install build-essential
This will ask you to insert ubuntu CD into your CD/DVD drive. Insert it.
Then
sudo apt-get install libc6-dev
will download and install dev package.
then
sudo apt-get install libssl-dev
will be required when you are trying to install Crypt::SSLeay etc.
Now you try sudo cpan
install (Package you wish to install)
I hope these steps will help you the most.

An IBM takeover of Sun Microsystems Inc would raise the prospect of creating a clear leader in computer servers, but gaining market share might not be what's behind IBM's expensive overtures in hard economic times.
Sun's software portfolio, including Java, MySQL and Solaris, offers IBM a chance to get an edge in nascent open source and "cloud computing" technologies that enable users to easily access applications over the Internet.
IBM may be betting that it can do a better job than Sun in taking advantage of such software, and use it to compete effectively against large technology rivals like Cisco Systems Inc and Hewlett-Packard Co.
Analysts said International Business Machines Corp doesn't need help in servers as it was already the world's largest vendor in the fourth quarter, with a market share of over 36 percent, according to market researcher IDC.
"They have a pretty good and complete line. They don't really need to add Sun. They could let Sun continue to wither and go its own way," said S&P Equity Research analyst Tom Smith.
An IBM-Sun tie-up would give the combined company more than a 40 percent share of the $53 billion market for servers. Top rival Hewlett-Packard currently has a 29 percent share, followed by Dell Inc, with under 11 percent.
A combined IBM and Sun would significantly change the balance of power in the $17 billion high-end Unix segment of the server market, where IBM and Sun were the top two players in 2008 with shares of 37 percent and 28 percent respectively.
Sources said on Wednesday that IBM was in talks to buy Sun. The Wall Street Journal said IBM was offering to pay between $10 a share and $11 a share, double Sun's Tuesday closing price of $4.97, or over $6.5 billion. IBM and Sun declined to comment.
EYES ON SOFTWARE
Software and services are already areas on which Armonk, New York-based IBM is focusing already, and they have helped the company maintain healthy margins and solid growth even as a weak economy has dragged down hardware sales.
Analysts said that the company was aiming to position itself for an economic recovery, as well as the next wave of the computing revolution, especially in emerging "virtualization" and "cloud" computing technologies.
Cloud computing and virtualization have become the tech industry's biggest buzzwords to describe systems that allow consumers, developers and businesses to use the Internet to access programs and data at remote computer centers.
As Internet traffic keeps growing on the back of online video use and social networking sites like Facebook, demand has grown for technology that helps save space and hardware.
Analysts said IBM is likely interested in Sun's Java software platform, as well as in MySQL, an open-source database used to run Websites that Sun acquired in early 2008. Open-source software allows users to access and modify source codes.
While Sun has failed to turn profits from its software portfolio, which also includes operating system OpenSolaris and off-site data storage company Q-Layer, analysts said IBM may make better use of them.
"They have more resources, more manpower, more expertise in more areas of the computing business all around. So they may be able to fit more
IBM pieces of the puzzle and come out with a better solution than Sun had," said S&P Equity's Smith.
Edward Jones analyst Andy Miedler also said he believes IBM is interested in expanding its software business, in addition to securing a bigger piece of the pie in the server market.
"Sun has been doing a lot in open source software. We think longer term IBM could be expanding there," he said.
NEXT WAVE OF COMPETITION
News of talks between IBM and Sun came after Cisco announced it would start selling servers aimed at data centers, by partnering with technology virtualization and storage companies like EMC Corp and VMware Inc.
The move will put Cisco in direct competition with IBM and HP, which are vendor partners. The budding rivalry, analysts said, may force them to acquire or ally with smaller firms to bolster their storage, security, and virtualization technologies so they can offer a broader set of products.
"When the economies pick up we believe corporations will be trying to improve productivity -- not by hiring or building plants but purchasing tech products; not just hardware, but also software, that enhances productivity," said Richard Sichel, chief investment officer at Philadelphia Trust Co, which owns IBM as well as HP shares.
Most analysts said they hadn't yet made up their mind on whether Sun was worth the hefty premium. Edward Jones' Miedler said IBM may launch massive cost cuts to make it worthwhile.
"How IBM would make this work financially is to significantly cut Sun's research and development and other overhead expenses, which would make IBM able to pay a premium and still potentially make money on the acquisition," he said.
But other analysts said IBM may actually want to keep Sun's R&D segment. "The batch of R&D computer scientists that maybe think a little differently to what IBM has done so far may give more things to mix together in the new generations of products," said S&P Equity's Smith.

IBM develops new protocol, users can talk to web
Giving a new dimension to the internet, the Indian research arm of the US-based IT giant IBM has developed a technology that will allow users to talk to the web and create voice sites using mobile phones.
"People will talk to the web and the web will respond. The research technology is analogous to the internet. Unlike personal computers it will work on mobile phones where people can simply create their voice sites," IBM India Research Laboratory Associate Director Manish Gupta told PTI.
For this technology, IBM has developed a new protocol -- Hyperspeech Transfer Protocol (HSTP) -- which is similar to the Hypertext Transfer Protocol (HTTP).
"India now has over 360 million cell phone subscribers. Last month we added 15 million," he said pointing out that the research technology targets ordinary mobile phone users, all of whom may not be literate.
The spoken web is a network of voice sites or interconnected voice and the response the company got in some pilot projects in Andhra Pradesh and Gujarat and the kind of innovations that people came up with were just mind-boggling, Gupta said.

Silicon Valley hit by mass layoffs
The recession turned up late on Silicon Valley's doorstep but is likely to stay awhile, as technology companies slash thousands of
jobs and rein in costs to make up for shrinking earnings and tight-fisted customers.
Job cuts in the technology sector have trailed other industries until recent weeks. Now they are coming fast and furious as the economic downturn grips the Valley, the strip of land in northern California that is home to household names like Google Inc and Amazon.com Inc units.
Tech giants like Intel Corp and Microsoft Corp are laying off thousands of employees, while start-up companies are firing in smaller numbers as they struggle to survive with fewer customers and venture capital dollars.
And this is just the start, analysts say, expecting thousands more to lose their jobs this year as the recession forces the industry to slash marketing and capital spending.
"Organisations are saying, 'What is the absolute nuclear winter? Let's plan for that,'" said Adam Charlson, senior partner at executive search firm Korn/Ferry International Inc, who works closely with the recruitment divisions of top tech firms. "What you're seeing now is organisations putting those plans into reality."
Last year, Silicon Valley lost 11,700 jobs, according to Steve Levy, senior economist at the Center for the Continuing Study of the California Economy (CCSCE).
The number is small compared to the 200,000 jobs lost after the dotcom bubble burst in 2000, but that is because the 2008 numbers don't reflect recent layoffs yet, he said.
"The headline is that the recession has hit Silicon Valley," Levy said. As a result, he said he was "substantially revising downward" employment predictions for 2009.
California's jobless rate hit a 14-year high of 9.3 per cent in December, significantly above the national average of 7.2 per cent, according to state officials.
Once bitten, twice prepared
Some analysts said they are reading the mass layoffs as preemptive acts by tech companies. When the
last recession hit, tech companies were too slow in cutting costs and laying off workers, said Andy Miedler, a senior technology analyst at Edward Jones.
But not this time, he said. "Layoffs and cost-cutting are unfortunate, but companies have to make tough decisions in a rough economy to preserve their own financial position."
Mark Cannice, a professor of entrepreneurship at the University of San Francisco, said Silicon Valley has been "inoculated to some degree" after the dotcom bust.
"Many firms didn't survive .... The ones that survived are much more efficient and resilient and were funded on sounder business models," said Cannice, who publishes a quarterly Silicon Valley Venture Capitalist Confidence Index.
But he said Valley companies are not entirely immune -- especially venture capital-funded start-ups. As large companies like Microsoft and Google cut back on spending, start-ups that supply them with software and other IT could run into trouble.
With venture capital funding falling 71 per cent in the fourth quarter of 2008 from a year ago, start-ups could be forced to fold up if they can't sustain their business and investors cannot fund them any longer. But mass layoffs in the tech sector need not necessarily be all doom and gloom. They could actually boost innovation as laid-off engineers, scientists and other highly skilled individuals decide to pursue their own ideas.
Calling it "forced" entrepreneurship, Cannice said he was optimistic that the current layoffs would "unleash the next wave of creative, thoughtful entrepreneurs."
Layoffs in the traditional tech sector could also spur employment in the alternative energy sector, recruiters said.
Neil Sims, managing director of executive search firm Boyden's technology practice group, said the so-called "cleantech" sector -- which employs environmentally friendly technologies -- will continue to grow and offer jobs. "It's not that the sky has fallen entirely," he said.

Lenovo to offer Linux on laptops
Lenovo, one of the world's biggest PC manufacturers, is to start selling laptops to business and consumers with Linux pre-installed on the machines.
Linux is a free, open source operating system developed as an alternative to systems such as Microsoft's Windows.
Novell will provide the Linux software on the laptops, which are due to go on sale at the end of the year.
Earlier this year PC maker Dell also announced it would start shipping PCs with the Linux OS installed.
Lenovo announced its plans at the start of LinuxWorld, an annual conference held in San Francisco.
Dell introduced Linux-powered PCs after chief executive Michael Dell asked customers for suggestions for new products on the company's website: Linux PCs were the most-requested item.
Linux was first released to the public almost 16 years ago and was developed by Linus Torvalds, who wanted to create a non-commercial alternative to an operating system used in many universities.
Linux can be freely distributed, modified and used by anyone who wants it. It is predominantly used to power web servers and while its growth on desktop computers has been limited to technology specialists, its adoption by Lenovo and Dell points to wider acceptance.
Analysts believe that approximately 6% of computers users run Linux, similar to the numbers choosing Apple Macs.
