GLX error

I recently upgraded to XFree86 4.0.2 and the newest NVidia Drivers. Nothing complained during install, but when I start X I get this:

dlopen: /usr/X11R6/lib/modules/extensions/ undefined symbol: __glNVScreenInfo

in reference to NVidia’s newest version of GLX. I can’t seem to find any reference to dependancies for GLX, so I don’t know where to look for this. I did a grep for the string glNVScreenInfo, and I got a hit on, but that is in my ld path.

Has anyone seen an error like this from GLX before?
