[Python-modules-team] Bug#509125: more information

[Yaroslav Halchenko]

Below please find extracts from our communications with the originator
of 599275 report:  as you can see -- find_util does not find .so.1 if
.so is not present... btw actually util seems not to be used (at least
directly) in python-opengl

$> grep util /usr/lib/pymodules/python2.6/OpenGL/platform/glx.py                      
import ctypes, ctypes.util
