nvidia issue: no compositing, libGLcore.so.1 not found

[Neal Becker]

Installed from rpmfusion:
xorg-x11-drv-nvidia-190.42-2.fc12.x86_64

Also 
xorg-x11-server-Xorg-1.7.1-7.fc12.2.rex.x86_64

Working, but compositing is disabled.

Looked at log, found:
(II) Loading /usr/lib64/xorg/modules/extensions/nvidia/libglx.so
dlopen: libGLcore.so.1: cannot open shared object file: No such file or 
directory
(EE) Failed to load /usr/lib64/xorg/modules/extensions/nvidia/libglx.so

Any ideas?

xorg.conf is default nvidia, with:
	Option	    "AIGLX" "on"
and
	Option	    "Composite" "Enable"
