It's quite likely that the numpy that you're seeing is that provided
with the system's Python. You can check by running
locate numpy
If what you see is in /System/Library/Frameworks/Python.framework, then
that's fine. There may be a way to tell where it comes from after
importing it from within the Python environment, but I'm not a Python
person so I don't happen to know how to do that.

Either use
/sw/bin/python2.6
as your command, or install the fink 'python' package, which creates a
/sw/bin/python that points to /sw/bin/python2.6. In either case, that
will automatically pick the right site-packages for you.
