Hmm.  I'm not sure I understand the easiest way to see the correct solution,
to these kinds of problemd.  It would be nice if there were a way to see
what
packages are available, but blocked by packages in higher priority repos, or
missing dependencies.

This reminds me of another related question but forgot to ask.

Don't remember exactly which distribution I was running at the time.
But I had problems with yum being unable to install certain packages,
because issues with complex dependencies were too difficult for it.
Someone suggested switching to the "smart" package manager,
which was smart enough to downgrade certain packages to resolve
dependency issues.  Have not seen signs of similar problems so
far with yum on CentOS.  Has yum caught up with "smart", or
are there still some issues here.
