I see. I got the impression that libGLU was still necessary separately 
because there was no /usr/libGLU.so.

Looking into XFree-4.2.0-r9.ebuild I see that you link to 
/usr/libMesaGLU.so . Why is that? In principle every application should 
link to /usr/libGLU.so.

Yes. The next XFree86 release will be based on Mesa 4.0 since that's what 
the current DRI CVS already has.

Thanks for the explanation. Making Mesa use the 'opengl-update' system 
seems a much better way indeed. But there's still the problem of GLU. It 
really shouldn't be included seperately by deprecated libraries providing 
"virtual/glut" , it should be managed by the 'opengl-update' script too.

GLUT is the only thing that is independent of the specific OpenGL 
implementation, being outside the scope of 'opengl-update'.
