The linker error I get is at the end of the FreeGLut > compilation. -lXext is trying to link in libXext.so and this should be in /usr/X11R6/lib. If the library's there then check the libraries in /usr/X11R6/lib are picked up (make sure /usr/X11R6/lib is in /etc/ld.so.conf and that ldconfig -v doesn't give any errors.) If it's not there add that line and rerun ldconfig. don't know off hand which RHEL rpm provides libXext if it isn't already there. HTH Huw
