 On my highly modified FC1 system with a 2.4.22 kernel and nvidia 6111
 video drivers where I've been running svn builds on a regular basis, I get
 a compile error with svn 14639:

 ccache g++  -o mythtv main.o    -L/usr/lib/qt-3.3/lib -L../../libs/libmyth

 ../../libs/libmythtv/libmythtv-0.20.so: undefined reference to
 `glXGetProcAddress'

 After some googling, I found this, wich suggests the solution -- I just
 don't know where in the code this change needs to be made to test it.

 Thread summary:

 Problem: undefined reference to 'glXGetProcAddress()' with Nvidia OpenGL
 shared libraries

 Solution: define GLX_GLXEXT_LEGACY to make the prototype for
 glXGetProcAddressARB() visible to the application, and use
 glXGetProcAddressARB instead of glXGetProcAddress
