So, the following oddities remain for Python2.3 :

Failed importing numpy.f2py.lib.extgen: update() takes no keyword arguments
ctypes is not available on this python: skipping the test (import error was: ctypes is not available.)
No distutils available, skipping test.

The missing ctypes shouldn't be a problem. I don't know what to make of the f2py import failure or if it matters. Nor do I understand what No distutils available implies. Anyone have ideas?
