[matplotlib-devel] Installation tips on Mac OSX 10.3

I just installed matplotlib-0.63.4 on Mac OSX 10.3, with some 
difficulties i detail (and answer) below.

Using Fink (0.7.1), freetype2 (2.1.3-21), Tk and GTK.

python setup.py install fails because of wrong paths to find freetype2 
ft2build.h. Darwin include paths (in setupext.py) are '/usr/local', 
'/usr', 'sw'.  freetype2 include paths are :

 > locate ft2build.h
 > /sw/lib/freetype2/include/ft2build.h
 > /usr/X11R6/include/freetype2/ft2build.h

Once '/usr/X11R6' or '/sw/lib/freetype2' to setupext.py paths for 
Darwin, build process works fine. Agg, GTKAgg, and TkAgg backends are 
available as described in your documentation.

I use matplotlib with ipython (python2.3.3, IPython0.6.3), and GTKAgg 
backend crashes if pygtk (2.0.0 here) is not build with threading. I 
used
 > python setup.py build --enable-threading

Thanks for this great matplotlib product.
