[Python-modules-team] Bug#590452: python-opengl: Needs freeglut3-dev installed for glut to work (e.g with bouncy)

[Bernhard Reiter]

Package: python-opengl
Version: 3.0.0~b6-3
Severity: important


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.

    _base_glutInit( ctypes.byref(count), holder )

this was from 
python y.py

from OpenGL.GLUT import *
from OpenGL.GL import *
def init():
     glClearColor(0,0,0,0)
     glMatrixMode(GL_PROJECTION)
     glLoadIdentity()
     glOrtho(0,1,0,1,-1,1)
def display():

     glBegin(GL_POLYGON)
     glVertex3f(0.25, 0.25, 0)

     glVertex3f(0.75, 0.75, 0)
     glVertex3f(0.25, 0.75, 0)
     glEnd()
     glFlush()

     init()

     glutMainLoop()

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.
