Re: [matplotlib-devel] OS X Leopard install, snag

[Boyd W. <bw...@nr...>]

As a general note, I built MatPlotlib-SVN on Leopard against the  
Apple Python, using the numpy, libz, freetype, and png that are  
included with Leopard.

It seems to work fine, superficially; I have not run extensive  
regressions with it yet.

I can send along a MacPorts portfile (including patches) tomorrow;  
(my Leopard problem is that SSH won't respond so I can't get to my  
office machine from  home).

I have some opinions about your other questions, the answers are to  
set specific environment variables.
However, my answers MIGHT BE WRONG because I can't test these at the  
moment (see ssh problem, above)

So take these responses with some skepticism. But perhaps they can  
point you in a helpful direction:

Hmm, what about setting a MACOSX_DEPLOYMENT_TARGET=10.5

I believe that "generic" autoconf would pick up CFLAGS:

CFLAGS="-arch ppc -arch i386"

Distutils uses ARCHFLAGS -- if you are using the Python from Apple  
Leopard:

ARCHFLAGS="-arch i386"
