1.1.0 (which was supposed to be 1.0.5 until recently) should be out
shortly. I can indeed verify that numpy.distutils does get imported in
1.0.4 but not in 1.1.0, so I think we've already fixed the problem on
our end.

<does some grepping> Ah. I found the source of the problem.
numpy.testing.numpytest, which gets imported when you import numpy,
uses a utility function from numpy.distutils in 1.0.4, but we changed
all that for 1.1.0.

Possibly, but 4.0.1 is the standard compiler on OS X. You probably
can't rely on anything else being installed.
