Dear pyopengl-users,
      I've write a script using pyopengl.arrays.vbo, it works fine. When I use pyinstaller to make exe, it got AttributeError. 
      And a same error report was found on stackoverflow:
      pyOpenGL exe made with PyInstaller gives attributeerror
      http://stackoverflow.com/questions/11011373/pyopengl-exe-made-with-pyinstaller-gives-attributeerror
      Is there any solution for this problem?
      Thanks!
