This assumes that you have grabbed a copy of the ubuntu hardy server
cd from the ubuntu.com website.
1. Install all dependent packages for CPAN
sudo apt-get install build-essential
2. invoke the cpan command as a normal user
$cpan
But once you hit on enter for “cpan” to execute, you
be asked of some few questions. To make it simple for
yourself, answer “no” for the first question so that
the latter ones will be done for you automatically.
3. Once the above is done, you will be present with the cpan
prompt. now enter the commands below
make install
install Bundle::CPAN
4. Now all is set and you can install any perl module you want. examples of what installed below
cpan prompt> install IO::File
cpan prompt> install Net::SMTP_auth
cpan prompt> Email::MIME::Attachment::Stripper
cpan prompt> Mail::POP3Client
