 Configuring for NVidia XVMC causes this failure:

 Quick and dirty hack:

 I know that's not a legit fix, however it works for my purposes.

 The only other strange thing I do is swap the order of two items in the
 configure script's detection of XVMC type. I've been doing this for years
 as it always finds XVMCW when I actually have xvmc NVidia.

 If I don't do that I get this when I run configure:

 {{{
 # Video Output Support
 x11 support      yes
 xrandr support   yes
 xv support       yes
 XvMC support     yes

 }}}

 Which is obviously wrong.

 This is a Gentoo install.

 If you need more information, please ask.
