You only need the Net:: FTP module installed on the client side as long as your ISP has an FTP daemon running. www.pair.net supports open source dev well with a php/perl/mysql/apache environment. They also provide free perl scripts and have most perl modules installed.

Check all the directories in @INC to see if you have the module installed  perl -e 'for(@INC) {print "$_ \n"}'. Consider using the CPAN module for installation as it tells you what you already have installed and if it is up to date.
