[Mesa-users] opengl shaders without dri

[Brian Paul]

If you run:

ldd `which glxinfo`

you'll see a list of the libraries that glxinfo (or any other GL app) 
is pulling in.  You're probably picking up an old libGL.so library.
You could try setting LD_LIBRARY_PATH to point to the location of the 
new libGL.so.
