[mythtv] libGL.so linking error when building trunk on openSuse 11.1, may be nvidia related?

The Nvidia binary driver package REPLACES some of the standard packages. 
If you have the '....run' package and extract it with 'Nvidia....run -x' 
  it will unpack itself and you can see, in the ../lib folder the 
libraries which it replaces.
Someone here posted a fix, which IIRC consisted of re-installing the 
mesa-libGL* packages. If you search this list at gossamer-threads using 
a search like "mesa-libGL NVidia driver" you should find what is needed.

I am not sure if mesa-libGL (plus ..libGLU ..libGLw etc) are enough. You 
may need to chase down what provides the packages which the Nvidia 
install replaces. If you do take that route, PLEASE post the list of 
removed files, and the packages which are required to re-instate them, 
on the VDPAU wiki page, where the warning about this behaviour of the 
NVidia installer is noted.

<semi-rant or request>
It would be SO nice if the Nvidia installer just RE-NAMED the files it 
touches, rather than just over-writing them. Even better if the 'run' 
package actually had a --uninstall switch.
Anyone at Nvidia read this list???
