RH 7 - need X 4.1.0 update help

I recently installed RH 7.0, and am enjoying learning it, but it doesn't support my Radeon VE in X. I downloaded the appro. packages for 4.1.0 (which is supposed to support Radeon cards), and installed per instructions. Now I can't X at all!
After startx, I get the following message about six times:
xauth: error while loading shared libraries: libXmuu.so.1 no such file or directory.

Help me X again!

The problem may not be with your video card drivers. libXmuu.so.1 library should be part of the xlibs package and should be loaded in /usr/X11R6/lib. You might give that a look. -mk

If it ain't broke, fix it till it is.
