XFree86: error loading glx

[Mitch Wiedemann]

My wife's computer is showing the following error in XFree86 Log:

(II) LoadModule: "glx"
(II) Loading /usr/X11R6/lib/modules/extensions/libglx.so
dlopen: /usr/X11R6/lib/modules/extensions/libglx.so: symbol _nv000344gl, 
version LIBGLCORE not defined in file libGLcore.so.1 with link time 
reference
(EE) Failed to load /usr/X11R6/lib/modules/extensions/libglx.so
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (loader failed, 7)

The box is running 2.4.22-1.2149.nptl.  I've read the NVIDIA_GLX/README 
file. I've un-installed the driver and removed all related files 
(mentioned in the README), and then re-installed.  The installer builds 
the kernel module, X runs without any trouble, just no glx (which means 
no Neverwinter Nights :( ).

My computer is running the same kernel, and is loading glx without any 
trouble, but I believe I installed the NVIDIA driver before I last 
updated the kernel. 
My XFree86 Log looks like this:

(II) Loading /usr/X11R6/lib/modules/extensions/libglx.so
(II) Module glx: vendor="NVIDIA Corporation"
    compiled for 4.0.2, module version = 1.0.5328
    Module class: XFree86 Server Extension
    ABI class: XFree86 Server Extension, version 0.1


I've searched all over the net, to no avail.  Can anyone shed some light 
on this?
