`Sudo pip install matplotlib` ne trouve pas les en-têtes freetype. [OS X Mavericks / 10.9]
J'ai déjà matplotlib-1.2.1 installé ainsi que numpy-1.8.0. Remarque - J'utilise le système python avec homebrew installé - j'ai $PYTHONPATH set so Python se charge depuis /Library/Python/x.y/site-packages (où pip s'installe).
Voici le code pour installer matplotlib (les configurations)
BUILDING MATPLOTLIB
matplotlib: yes [1.3.1]
python: yes [2.7.5 (default, Aug 25 2013, 00:04:04) [GCC
4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)]]
platform: yes [darwin]
REQUIRED DEPENDENCIES AND EXTENSIONS
numpy: yes [version 1.8.0]
dateutil: yes [using dateutil version 1.5]
tornado: yes [tornado was not found. It is required for the
WebAgg backend. pip/easy_install may attempt to
install it after matplotlib.]
pyparsing: yes [pyparsing was not found. It is required for
mathtext support. pip/easy_install may attempt to
install it after matplotlib.]
pycxx: yes [Couldn't import. Using local copy.]
libagg: yes [pkg-config information for 'libagg' could not
be found. Using local copy.]
freetype: yes [version 17.1.11]
png: yes [version 1.5.17]
OPTIONAL SUBPACKAGES
sample_data: yes [installing]
toolkits: yes [installing]
tests: yes [nose 0.11.1 or later is required to run the
matplotlib test suite]
OPTIONAL BACKEND EXTENSIONS
macosx: yes [installing, darwin]
qt4agg: no [PyQt4 not found]

pdftops: no
Et plus tard, après avoir copié et créé des fichiers, il arrive à build_ext et échoue en raison de fichiers d'en-tête manquants.

J'ai eu le même problème et j'ai finalement trouvé la solution en vérifiant les commandes de compilation. C'est vraiment simple:
ln -s /usr/local/opt/freetype/include/freetype2 /usr/local/include/freetype
