Hi William,
There is a company, Enthought, which offers a free package installer, which comes with 6 "essential" python libraries, including matplotlib.
If you have an "edu" email account (you are an academic, or do academic research at a gov lab, like LBL) you can download their full set of libraries
http://www.enthought.com/products/edudownload.php
If not, and you think it is worth it (or can get your company to pay), starting at $199 you can download their package installer (and get their tech support).
Couple words about them: I have no affiliation with them. Some of their original employees were deeply involved in numpy. They developed a 3D plotting library, Mayavi, which is pretty cool.
I am reasonably comfortable with my mac, installing src code etc. I used to install everything myself (back on OS X Tiger). Then, when I upgraded to Snow Leopard, I couldn't get it all to work out - I did an account migration from old to new, and then there were some issues (I think) relating to the 32 vs 64 bit compatibility that I couldn't resolve. I went to a friend who is good with computers to get help - he said "You should just use the Enthought installer - its so easy, that is what I do". That helped me get over feeling like I had to do it all myself. (Of course some day, when I have heaps of free time and no pressure from work, I will sort out how to do it all myself again....)
I am guessing if you want to link numpy against the full BLAS/LAPACK libraries for optimal speed on matrix manipulation etc, then you may need to do the installation yourself, including all the fortran libraries. But at least with their package installer, it should work out of the box. Also, it installs the whole suite as a "Framework" in /Library/Frameworks/Python.framework/Versions/ with a cleverly chosen Version so as not to mesh with your own installation. So you can install there version, based on 2.7 and your own version 2.7 and they won't interfere. You'll just have to relink the /usr/bin/python and /usr/local/bin/python to which version you want.
Good luck,
Andre

Hello mat plot lib users!
I feel quite embarrassed that I’ve gone through 2 days of trying to get to get numpy, scipy and matplotlib all to work nice with each other. I’ve scraped through forums, stackoverflow and all the links that can bide me some type of logic. Yet, alas I still fail wildly with this set of errors:
my current status is: just did a fresh install of my lion os and haven't installed Xcode yet. I'm a little lost and have found only macports, homebrew guides online only to be a slower failure. I really need to use this software but I'm finding it difficult keeping straight what order and what I need to install. Is it best to have python 2.6 or 2.72? if it's 2.72 should it be the universal version from python.org? Once that is installed is it best to just install numpy and scipy from github and then try matplotlib? I know I need to install fortran and make sure that it's using G++ 4.2 and C++ 4.2 BEFORE i run scipy and numpy setup... Yet, right now I'm floundering for a clear example on 10 or so commands I should put into terminal and in the correct order for how to install it. I promise once I learn how to install I'll put a resource on the web or link back to some of the better resources. As for now my freshly installed os computer is in your hands currently with python 2.71 that was preinstalled with Lion. That is all I've done thus far.
Thank you !
Here is the old error I was getting when I used the home brew guide that I found here: bit.ly/qGdKy9
