Thanks for this information; that site certainly looks interesting.  I 
will look at it more carefully as I'm developing software at the NOAA 
Space Weather Prediction Center <http://www.swpc.noaa.gov/>.

Christoph Gohlke determined that if I upgraded from numpy 1.3 to 1.4, 
f2py would successfully find and use the Intel Fortran compiler which 
was my preferred choice all along.
