if you installed perl, chances are you already have CPAN installed. you just need the right command.
invoke CPAN such::
you@linux $>perl -MCPAN -e shell
then be prepared for a bunch of questions you can usually answer with 'enter'.
after you select your location it will ask which site you want CPAN to check for whichever module you want. type in: 1 2 3 4 ... to around 9. that way you'll be sure to get connected to at least one d'load site.
