So I had a similar issue for the pst week on my desktop machine.  At some
point updates did not get applied right. Either I accidentally rebooted the
system while updating or something else messed up.  I could not update
several of the packages that claimed they were missing files or
prerequisites.  If you run " rpm -Va --nofiles --nodigest" and you see
"Unsatisfied dependencies" error messages, then you might have the same
issue I had.

Now if that is the case you will need to re-download and reinstall the
software and you might have to force the re-install of those packages.  Now
you should just have to re-download the dependancies of the packages you
need to get everything updated to the current level.
