When I try to import cgkit.all (or some of the other packages) I get this error message:

  File "E:\desk\krychu\demo\src\CelShadingEffect.py", line 6, in <module>
    import cgkit.all
  File "C:\Python25\Lib\site-packages\cgkit\all\__init__.py", line 54, in <module>
    from cgkit.scene import Scene, getScene
  File "C:\Python25\Lib\site-packages\cgkit\scene.py", line 41, in <module>
    from Interfaces import ISceneItem
  File "C:\Python25\Lib\site-packages\cgkit\Interfaces\__init__.py", line 37, in <module>
    from isceneitem import ISceneItem, ISceneItemContainer
  File "C:\Python25\Lib\site-packages\cgkit\Interfaces\isceneitem.py", line 37, in <module>
    from protocols import Interface
ImportError: No module named protocols

Am I missing something? I can't figure out what is the problem. I'm using the latest cgkit version and Python 2.5.

Thanks in advance
best regards,
