To follow up on this, I have tested the following configurations (MacOS 
X 10.6.8 with MACOSX_DEPLOYMENT_TARGET=10.4):

build numpy 1.6.1fc3 from source: the only case that shows a problem. I 
built this numpy twice and both times saw the problem.

The following did not show the problem:
build numpy 1.5.1 from source
install numpy 1.5.1 using binary installer
install numpy 1.6.0 using binary installer

I also noticed that the module with the failing import 
(distutils/ccompiler.py) is identical in numpy 1.5.1 and 1.6.1fc3.
