Hi, e-ferrari, welcome to the Monastery!

If you're not in a giant hurry, you might want to consider deleting your current CPAN local mirror, if any, and rebuild it. The instructions are in module CPAN::Mini, but some time ago I extracted just what I need to create my own local mirror. I'll be glad to revisit it and post it here if you want.

Another reference I used was http://perladvent.pm.org/2004/5th.

UPDATE: Are you running the code you showed as root or as a normal user?
