Best Method for installing Perl Modules

Which is the perferred method of installing Perl modules on a Unix system? Is is CPAN or manually installing them via a tar file? Also can anyone point me in the right direction to a decent "how to" on configuring CPAN and how to perform custom installs from a tar? thanks:b:

It's more about what you are comfortable with. Usually, it's a lot quicker to install using CPAN if you're installing more than a couple of modules or if there are numerous dependencies.

See:

CPAN - query, download and build perl modules from CPAN sites

I will take a peak. thanks
