`Sudo pip install matplotlib` fails to find freetype headers. [OS X Mavericks / 10.9]
I already have matplotlib-1.2.1 installed as well as numpy-1.8.0. Note - I am using system python with homebrew installed - I have $PYTHONPATH set so Python loads from /Library/Python/x.y/site-packages (where pip installs to).
Here is the code for installing matplotlib (the 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]
gtk3agg: no [Requires pygobject to be installed.]
gtk3cairo: no [Requires cairo to be installed.]
gtkagg: no [Requires pygtk]
tkagg: yes [installing, version 81008]
wxagg: no [requires wxPython]
gtk: no [Requires pygtk]
agg: yes [installing]
cairo: no [cairo not found]
windowing: no [Microsoft Windows only]
OPTIONAL LATEX DEPENDENCIES
dvipng: yes [version 1.14]
ghostscript: yes [version 9.02]
latex: yes [version 3.1415926]
pdftops: no
And then later down the line, after copying and building files, it gets to build_ext and fails because of missing header files.

Answer
I had the same problem, and finally found the solution by checking the compilation commands. It's really simple:
ln -s /usr/local/opt/freetype/include/freetype2 /usr/local/include/freetype
