Yes, I think it should be.  Just download this:

  http://www.geuz.org/gl2ps/src/gl2ps-1.1.2.tar.gz

untar it, 

 $ cd gl2ps-1.1.2

 $ gcc -O3 gl2psTest.c gl2ps.c -framework OpenGL -framework GLUT \
 -framework Cocoa

Now, run ./a.out and press 's' to save a bunch of eps files.  I think
you'll see no shading for the torus (or teapot).  If that is the case,
I think you can tell the developers this and tell them that their
OpenGL implementations is broken.  Specifically its broken when
glRenderMode is set to GL_FEEDBACK and no shading information appears
to make it into the feedback buffer.  Christophe, please correct me if
I'm wrong.
