Strange, it should look in <ProjectRoot>/lib/modules/dri/ . Seems it didn't
pick up the right libGL.

What's your hardware? Jack Howarth used to have similar problems with the old
driver, but AFAIR it was because he tried to build things with the Red Hat
following the Red Hat procedure.

I wouldn't waste too much time to figure that out (if it works at all) because
this will eventually be in the standard XFree86. For now, I use a symlink for
r128_dri.so and set LD_LIBRARY_PATH.
