OK I tested with the simple fix,
if sys.platform.startswith('linux') : from OpenGL import GL
and it worked. Also as Florian suggested, using --exclude-module=OpenGL
when building with PyInstaller for other platforms takes care of that issue.
I poked around inside Ubuntu 16.04 (64-bit) looking for libGL.so and there
is just a mess of them.
/usr/lib/x86_64-linux-gnu/libGL.so -> mesa/libGL.so
/usr/lib/x86_64-linux-gnu/mesa/libGL.so -> libGL.so.1.2.0
Since the original Ubuntu bug report (linked earlier) said the problem was
using the "mesa" libs, and since I don't see anything nvidia-related dlls
-- and since the import work-around fixed it -- I didn't want to mess with
that. Perhaps ctypes.cdll.LoadLibrary("libGL.so.1") would pick up the last
one, libGL.so.220.127.116.11.32651, but I don't know.
