Sudo pip安装matplotlib无法findfreetype头文件。
我已经安装了matplotlib-1.2.1以及numpy-1.8.0 。 注意 – 我正在使用安装了自制软件的系统python – 我有$PYTHONPATH设置，以便从/Library/Python/xy/site-packages （其中pip安装到）加载/Library/Python/xy/site-packages 。
这里是安装matplotlib的代码（configuration）

然后，在复制和构build文件之后，它会转到build_ext并由于缺less头文件而失败。

我有同样的问题，最后通过检查编译命令find解决scheme。 这很简单：
ln -s /usr/local/opt/freetype/include/freetype2 /usr/local/include/freetype
