I frequently use the cpan upgrade command to bring my Perl modules to their latest versions. Regrettably on distributions like CentOS which use ancient versions of Perl it attempts to upgrade perl itself along with other modules like B::X. Is there some way I could combine the ease and power of upgrade but not attempt (and fail) at upgrading core modules? Thank you.

Don't use the system perl. Install your own and start from that. Even when there isn't an ancient perl.
You will have to exclude not just core modules, but also distributions that depend on newer versions of core modules, and distributions that depend on those distributions... It's a battle you can't win and shouldn't even try to.
BTW, the CPAN-trying-to-upgrade-perl bug was really really ancient; are you really seeing it?
