well the glsl programm is compiled and linked using openGL.
if your card/driver does not support the instructions in your glsl 
program, then you Gem cannot do anything about it.
try upgrading your driver. and then your hardware.
if it still fails (and it works somewhere else, which it should at 
least on the original authors machine), file a bug-report at nVidia!
