Re: [Matplotlib-users] problem building on mac (ppc arch issue)

If your goal is to build only for Intel, edit the Makefile inside your
(wherever your python installation is)/lib/python2.5/config directory
and delete "-arch ppc" everywhere you see it. Then try a clean build
of matplotlib. I'd make a backup copy of the original somewhere just
in case something goes wrong in editing the Makefile, though. You
don't need to worry about the -Os optimization flag unless you're
running Leopard, in which case setup.py has a build_osx105 target that
will handle that for you. Given your arch issues, though, I'd edit
setup.py in the matplotlib source and take out the -arch ppc flags
there too if you decide to use the target.
