Kivy.app 1.4.1 lacks modules PIL and cv

Trying to run the examples/demo/camera_puzzle.py on Mac OSX 10.7.5 Lion, I get ImportErrors:

This happened on a machine without a camera attached, so running a camera-oriented application does not really make sense. A check on availability of a camera and corresponding response would be nicer, though.
Also, kivy 1.4.1 is superseded as well.
