[CentOS] Yum out of sync?

Sounds about right. You might also consider hunting for conflicting
software installed via source build as well. The two have a tendency
to go together...

Yep.

Yeah, you have to, or yum would fail. the repo section can be in
/etc/yum.conf, or for newer yums in /etc/yum.repos.d. Basically it's
the section with the [repo-id] name=foo baseurl=somepath, etc.
Sometimes when people have trouble updating it's because they're
either not using the updates repository, they've hardcoded something
that doesn't exist anymore, or something is otherwise fouled up. Good
work in fixing it.
