This could be from some combination of the oracle linux junk or something else.

Why are you mixing architectures? Why did you not get the x86_64 packages? > > rpm -ivh –-nodeps --force *rpm This is an amazingly bad way to install packages. Using --nodeps and --force will quickly cause system breakage, as you've discovered. The errors that installing the rpms you got would have kept you from breaking your system in such a fashion. > Any one knows any thing wrong with it?
