Yes but this don't care. Linking for one libGL (from mesa3d) or for
other (from nvidia) crash when run fakeroot with libGL from nvidia.
To clarify:
Compile "hola" with libGL from mesa3d or with libGL from nvidia, and the
run inside fakeroot with a libGL from mesa3d installed in the system NOT
crash.
Compile "hola" with libGL from mesa3d or with libGL from nvidia, and the
run inside fakeroot with a libGL from nvidia installed in the system CRASH.
