GLUT is part of mesa.  I.e. whatever it needs is available under linux.

Heh, well there's a bit more to it then that.  Not sure exactly how the 
remote GLX works, you might require a few non-mesa bits but I believe 
they do exist.  

In any case GLUT is definitely available as a part of Mesa.  I've
compiled 3d applications that require it.
