Not as far as I know -- I always erase the directories by hand.

python setup.py install --prefix=${HOME}/test_install


export PYTHONPATH=${HOME}/test_install/lib/python2.5/site/packages:${PYTHONPATH}

Now you can run Python, import numpy, and execute the test suite.

I don't export that variable on my system, but I have very little
experience with building on OSX.
