yup -- that is probably the python.org python.

However, there are now two different builds of 2.7 for OS-X the "10.3" 
one, which is 32 bit, PPC+Intel, 10.3.9 and above, and the "10.6" build, 
which is 32bit_64bit, Intel only, and only runs on 10.6 and above.

You need a numpy build that matches the python build, I suspect you have 
a mis-match. Check carefully which ones you downloaded and make sure 
they match.

No. The "System Python" term is a misnomer that somehow has never gotten 
fixed in the installer -- what it is really looking for is the 
python.org build.
