perl -MCPAN -e shell
(but using CPAN to update perl will break things)
I use CPAN all the time and haven't had any problems. Are you saying this because yum/rpm wouldn't know they were installed? Can you expand on your concerns?
That's one issue, the other is if there is ever a perl upgrade upstream, you'll have to figure out what modules were installed via CPAN and rebuild them. Admittedly that's not a huge problem, since upgrades to perl don't happen that often.
There are a couple of CPAN->RPM type programs out there. They're not perfect, but at least you can keep track of things in the RPM database that way.
