Strange, you are the second person to report this.

http://elrepo.org/bugs/view.php?id=425

I am unable to replicate the issue - the symlink is fine on my system 
after updating.

$ ll /usr/lib64/xorg/modules/extensions/nvidia/
total 9588
lrwxrwxrwx. 1 root root 16 Nov 8 16:18 libglx.so -> libglx.so.331.20
-rwxr-xr-x. 1 root root 9815912 Nov 8 15:52 libglx.so.331.20

Did you reboot after updating the nvidia drivers? That was the cause of 
the issue for the previous report.
