Problems running Demo_OgreCollision01.py

Hello, frankly I'm a bit new to Python as well as to Ogre, so it's quite possible that this is a simple and obvious problem. The other demos work just fine and I've been having good luck with running and extending them, but this one gives the runtime error:

AttributeError: 'module' object has no attribute 'MeshToShapeConverter'

What might be causing this?

There are a couple of "Demo_OgreCollision..." files (demos/ogre, demo/opcode etc) -- which one are you trying, AND it's simply possible that the one you are testing was never finished...
