I’ve killed half a day trying to compile matplotlib for python on Snow Leopard. I’ve used the googles and found this helpful page (http://blog.hyperjeff.net/?p=160) but I still can’t get it to compile. I see comments from other users on that page, so I know I’m not alone.
I already installed zlib, libpng and freetype independently.
I edited the make.osx file to contain this at the top:
PREFIX=/usr/local
PYVERSION=2.6
PYTHON=python${PYVERSION}
ZLIBVERSION=1.2.3
PNGVERSION=1.2.33
FREETYPEVERSION=2.3.5
MACOSX_DEPLOYMENT_TARGET=10.6
## You shouldn't need to configure past this point
PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig"
CFLAGS="-Os -arch x86_64 -arch i386 -I${PREFIX}/include"
LDFLAGS="-arch x86_64 -arch i386 -L${PREFIX}/lib"
CFLAGS_DEPS="-arch i386 -arch x86_64 -I${PREFIX}/include -I${PREFIX}/include/freetype2 -isysroot /Developer/SDKs/MacOSX10.6.sdk"
LDFLAGS_DEPS="-arch i386 -arch x86_64 -L${PREFIX}/lib -syslibroot,/Developer/SDKs/MacOSX10.6.sdk"
I then run:
sudo make -f make.osx mpl_build
which gives me:
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig" &&\
export MACOSX_DEPLOYMENT_TARGET=10.6 &&\
export CFLAGS="-Os -arch x86_64 -arch i386 -I/usr/local/include" &&\
export LDFLAGS="-arch x86_64 -arch i386 -L/usr/local/lib" &&\
python2.6 setup.py build

I’m just lost.
According to your error message you have missing freetype headers. Can you locate them using system search functionalities. I will not lecture on using a pre-built package since I love scratching my head and compiling from the start as well.
