This is why i use perlbrew on every system i develop on now. Not only does it allow you to control what versionS of Perl you want to work with, it also provides a ready-to-use cpanm client which is a vast improvement over the old interactive CPAN client. cpanm does a pretty good job of removing CPAN modules too.
