When trying to start a python-opengl appliction that uses (free)glut
you get a traceback if you do not install freeglut3-dev.
However I do not think that installation of freeglut3-dev should
influence the runtime system. Or it must be added to the dependencies.

Maybe the defect is already fixed for newer versions, I did browser a number
of problem reports, but I did not find one that fitted good enough
for this info to go in.

this was from
python y.py

Starting bouncy will have the same effect.

Until you install freeglut3-dev, then startup works,
though some texts are still not displayed for me, which could be
a hint towards that this only fixes the error reporting
and still another package is needed.
