nVidia's script does Bad Things(tm), I'd only install their driver  
from a package that takes precautions to avoid said Bad Things(tm) --  
i.e. puts their libs in a location that doesn't overwrite system libs  
and make them accessible using ld.so.conf and xorg module path tweaks.

I believe xorg-x11-drv-nvidia-libs-devel was actually the package you  
needed to build VDPAU support. That, or the not-yet-in-the-repo  
libvdpau-devel, which is what I build my own svn trunk vpdauified  
packages against.

rpmbuild --without nvidia ... should have done the trick, I think.

You installed nvidia's binary driver from their scripts, which  
overwrote the stock opengl libs. Do not pass go, do not collect $200.  
And/or reinstall the relevant distro packages to get back the stock  
versions. For /usr/lib64/libGL.so, that would be mesa-libGL-devel, I  
believe.
