In the c++ examples, one of the ideas of the CMakeLists.txt section is
to attempt to catch this type of "you didn't compile VTK with the
right options" problem. Since there is nothing similar for Python, I
added a "Build Requirements" section:

http://www.vtk.org/Wiki/VTK/Examples/Python/vtkCompassWidget

Maybe we also need to have a "minimum VTK version" section in all (c++
and python) examples to catch this sort of thing?

Thanks,
