Installing numpy on 2.7 (OS X 10.7)

[jefflovejapan]

I'm following the instructions given <href="http://www.scipy.org/
Installing_SciPy/Mac_OS_X">here</href>, but it isn't working.
Specifically, I'm getting:

Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/
Contents/MacOS/Python: can't open file 'setup.py': [Errno 2] No such
file or directory

even though I completed the two downloads from github successfully.
Any ideas why this wouldn't be working, or any ideas where I can look
for better instructions?
