I'd disagree here, but am happy to be wrong.
With apt you can have many repository sources, they are all searched for
the highest-version number when you ask to install a given package.
With CPAN.pm you give it a list of repositories, but that's only for
high-availability. The module gets an up-to-date module list from the
first repository that is willing to give it. Recently the repository
I've been using here in .au stopped updating and so I had no new sources
since December 18th. CPAN.pm gave me a warning, but didn't bother
checking any other mirror for a more up-to-date list.
When I ask to install a module that list is considered canonical.
CPAN.pm does not check any other repository for any other version. You
cannot set up a new CPAN repository with a single module and put that at
the top of your urllist, and have all other modules installed from the
second preference.
Many apologies if I'm wrong :)
Cheers!
