Actually, the older RPMs seem to have a dependency on XFree86, versus the installed X.org
What I ended up doing is downloading and installing from povray.org (
http://www.povray.org/download/ ). I was astonished at how easy it was!! (usually ./configure make make install has some hiccup or other when I try it, but their "install" script worked smoothly) I still would much prefer to have everything handled through package management for one place to look to uninstall, upgrade, etc.
Anyway, it's all fixed now, and I've done a few renders already..
Thanks for your reply.
