CPAN (Comprehensive Perl Archive Network) is a very nice way to manage your Perl modules. You can easily install a new Perl module:
perl -MCPAN -e 'install Net::Twitter::Lite'
On my machines running Perl 5.8.8, the Net::FTP as well as the LWP methods failed to download files from the CPAN mirrors.
Fix: open /usr/lib/perl5/5.8.8/CPAN/Config.pm in your favorite text editor and change the dontload_hash value to read as follows:
dontload_hash => { "Net::FTP" => 1, "LWP" => 1 },
This disables the Net::FTP and LWP methods, reverting to wget.
Next, have the CPAN module update itself.
perl -MCPAN -e 'shell'
cpan> install Bundle::CPAN
cpan> reload cpan
Enjoy!
Edit: fixed code formatting.
