It appears that your software uses Open Scene Graph, which has a
dependency on the GLUT library.  gtkglext doesn't depend on GLUT, so you
clearly have configuration/link problems that are not related to gtkglext.

In this case it looks like you need gtkglext 1.2.0 ... this release
fixes problems compiling GtkGLExt against GTK+ >= 2.8, caused by the
separate pangox library.
