to replace only libglut.so is not enough. if i understand you correctly, you changed the backend without the API. (you need .h at compiletime, .a (an archive of .o files) when you link everything to an executable, and .so at runtime.)
my libglut installation comes with...

/usr/lib/libglut.so.3 (link to .3.8.0)
/usr/lib/libglut.so   (link to .3.8.0)

i guess, you have to recompile Graphics.UI.GLUT, too.
