It's easy to understand:

    .../python2.x/site-packages/PythonCAD.pth:
        PythonCAD

    .../python2.x/site-pachages/PythonCAD/
        Interface
        Application

Having PythonCAD's Interface in the global namespace is naughty.

Done here. It appears to work -- as far as 

    from BTrees import OOBTree 

works. Is that good enough?

Take care,
