On one computer, I was having some problems running yum upgrade. It would complain that a dependency wasn’t installed. However, I could rpm -q that dependency and it showed up fine. To fix this, simply uninstall the package that was the dependency and then run upgrade. That should cause the dependency to be automatically downloaded and installed.
