I'd say libGL.so is doing dlopen( "modules/dri/r128_dri.so", ... ) and
thus picking up the first instance of that in the dynamic loader's
path.  Similarly, applications linked with -lGL will pick up the first
instance of libGL.so, not necessarily the one residing under the current
X server's ProjectRoot directory.

It's very important you have ld.so.conf set to pick up the correct
version if you haven't installed the DRI-enabled X server in /usr/X11R6.
