[SciPy-User] recipe for installation on Mac OS X?

[Jeremy Conlin]

I know I'm a bit late to this email chain, but I have succeeded in
installing Python 2.7.1, numpy, scipy, matplotlib on Snow Leopard.
The instructions I used are attached.  I had to follow these
instructions because I don't have root access to my machine and needed
these updated libraries.  This allowed me to have 32 and 64 bit
(universal) binaries of Python 2.7.1 and have everything else match.
All the tests for numpy and scipy worked for me.

As a side note, these instructions also work for installing numpy and
scipy on Python 3.2 which was just released on Sunday.  I have not
tried the development branches of matplotlib or iPython.

Hope this helps.
