Thanks for this.  That was a help to distinguish files from directories.

The problem was I had an old NVIDIA driver, 5336, coupled with a mix of 
NVIDIA standard install vs Gentoo installations of the shared objects, .h 
files, etc.  (Gentoo uses ebuilds called nvidia-kernel or nvidia-glx  while 
NVIDIA runs a shell script.)

The solution was to upgrade to NVIDIA driver 6629 
(NVIDIA-Linux-x86-1.0-6629-pkg1.run
from the NVIDIA download site), from the existing 5336.

This solved a number of symptoms that arose:  undefined symbol 
glBlendEquationSeparateNVX, API mismatch NVIDIA Kernel module vs X  module,  
and the famous "Could not find a decent visual" error.
