installing numpy on Tiger

Hi Alan -

I have not had luck with the binary distros.  There is always
something that doesn't work, so I will be interested in
the results of your efforts.

The biggest problem with compiling things yourself is going
to be dealing with LAPACK and fortran issues, and the
backends in matplotlib.

FWIW, the most stable solution I have found that doesn't involve
dealing with dependencies yourself is darwinports (now
macports).  It currently has 1.0b5 numpy and scipy 0.5.1, which
depend on python 2.4. Matplotlib worked with the wxPython
backend but not others.  While not the latest versions it will get
you started, and I would guess 1.0 will be available soon (anyone?).
I had absolutely zero problems using this once I realized that I
had to use wxPython for the plotting backend.  The snag
is that gfortran is needed, which requires compiling gcc 4.0 which
took 6 hours on my powerbook, so you will need some patience.
