I believe the error message is misleading (a known bug). From the path 
you are probably running python.org python (though it could be 
ActiveState or built from source).

Assuming it really is python.org, the next question is: which of the two 
flavors of python.org Python do you have: the "10.3" version (which is 
32-bit only, but very backward compatible), or the "10.6" version (which 
includes 64-bit support but requires MacOS X 10.6 or later)?

There is a separate numpy installer for each (and unfortunately they are 
not listed near each other in the file list). Maybe you got that match 
wrong?

If in doubt you could reinstall python from python.org.
