If you were able to install python without sudo you should not need to 
use sudo to build numpy. I certainly did not need to do so. Can you post 
the exact sequence of commands you ran?

It is not obvious to me, but I do't see what is wrong either. Apple's 
python is not in /usr/local, so it does not sound like when you build 
numpy you ended up using the "wrong" python.
