I am trying to install matplot on an OS X (10.5.7) Intel MacBook.  I
cannot build the matplot lib extensions.  I get the following error:

....

This is matplotlib-0.91.4.  I get the same error whether I install via
the egg or download the zipped tar ball and run "python setup.py
build".

The libraries in "/sw/lib" were installed by the fink package manager.

In particular I don't understand the error message about
libiconv.2.dylib being "not of required architecture for architecture
ppc".  It seems like matplot lib thinks it's building on a PPC instead
of an Intel machine.

I'm running Active State Python 2.5.4.

Any suggestions for how to get matplotlib working on my machine?

Thanks.
