Here's where you went wrong. You want:

setenv PYTHONPATH /usr/local/lib/python2.3/site-packages

Note that you're actually importing a numarray within numpy's directory
structure. That's because of your PYTHONPATH. numpy ships numpy.numarray
to provide backwards compatibility. To use it, you must do "import
numpy.numarray as numarray"

Cheers!
