[SGVLUG] How do you use yum/dnf across major versions?

[Matthew Campbell]

CPAN is not recommended for Perl on RH based distros as dependency
tracking is not handled properly.  If you install through yum or dnf
you won't have a future update cause incompatible versions to be
installed.

Also CPAN is not trivial to get to work properly, you end up spending
a lot of hours monthly in build maintenance instead of application
deployment.  Stable packages from the repos are the way to go (at
least as long as they are supported by RH :(  ).
