I just started this at $WORK, although I'm changing the %_prefix of the
packages so mine wouldn't help you much.
Biggest problems I've had:
1) Circular dependencies in the RPMs.
(Test::MinimumVersion vs. Perl::MinimumVersion, for example.)
2) CentOS 5 'rpm' can't handle Fedora 13 SHA hashes.
(Solution: Rebuilt Fedora 10 SRPM for 'rpm'.)
3) Fedora 13 .spec files assuming man pages are compressed.
(Solution: Edit .spec ".3pm.gz -> .3pm*" and 'rpmbuild -ba .spec')
4) Some CPAN modules need newer versions to pass tests.
(Downloading the new .tar and upping the .spec version is easy though.)
5) XML::Parser will fail its tests due to Fedora patches.
I also plan to add a patch of my own from
94fa954eaae532928977ae7f7290536783269b6e.

Ones I've filed bugs for they've been responsive to. Of course you could
volunteer to help too.

We switched from 5.8.4 to 5.10.0 without issues (other than #60508 which
was infrequent) and given the extra attention on 5.12 I'm confident it
won't be more surprising.
