For those who would like to avoid 'exec', here's the equivalent using
__import__:

    m = __import__('paraview.vtk.%s' % moduleName, globals(), locals())
    try:
        attrlist = m.__all__
    except AttributeError:
        attrlist = dir(m)
    for attr in attrlist:
        globals()[attr] = getattr(m, attr)

It doesn'appear that VTK sets __all__, so that should be able to be
removed.
