You don't have to do everything that I did, but I have libpng and whatnot installed in /usr/local for other purposes anyway, and I didn't have a particular need to build a universal binary version of matplotlib. Furthermore, using GCC 4.2, while forcing one to get rid of Wno-long-double (an Apple-only thing anyway, and I think it's bad practice to include assumption of such options in a Makefile), allowed me to keep -O3 since it does not have that particular bug. So IF you want to keep the O3 optimisation, then you should install the 4.2 compiler, make sure it gets used, and eliminate the -Wno-long-double flag from the Makefile. No other changes necessary relative to the standard instructions. I've filed a bug report with Apple about the problem with their GCC 4.0.1 in Xcode 3, and as soon as I can get my bug reporting ability up and running again (login has been wonky lately), I'm following up with some additional information they asked for. I'm sorry if I caused some confusion with my personal preferences.
