Some CPAN setup that I often do on a new computer.
Suggested CPAN options
o conf auto_commit 1
o conf commit
Automatically save preferences.
o conf prerequisites_policy follow
o conf build_requires_install_policy yes
Allows you to install larger packages like Catalyst etc without manual intervention, so you can let it sit and do its thing.
o conf make_install_arg UNINST=1
(if all hope is lost) to choose a new mirror
choose a random one from here
o conf init urllist
