A good thing to try is deleting both the build directory and the numpy
folder in site-packages just to make sure you are starting with a clean
slate. Then try the install again. You should also run which python just to
make sure you are using the right python, not that that seems to be the case
here. Also, put the build output into a log file like so: $ python setup.py
build &> log.txt. Then zip and attach the log to your post so we can get a
better idea what is going on.
