Seems sad that no one's responded to your e-mails, but apparently you have everyone stumped.
I don't know exactly what would have caused the problem either, but in this situation I think I'd remove the rpm package (#rpm -e rpm), download the source, compile it, and then install it.
Also, make sure all dependencies are taken care of too. If you upgraded your kernel using an rpm, then it might have an unsatisfied dependency that is causing your problems. And that dependency may not be just with the rpm package that you have installed.
