发现 OS X 10.10 使用 pip 或者 setuptools 的一个坑

如果package需要调用clang就会出错。

clang -fno-strict-aliasing -fno-common -dynamic -I/usr/local/include -I/usr/local/opt/sqlite/include -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/usr/include/libxml2 -I/private/var/folders/l9/9nvxswk920qb6wh37gt_v9d40000gn/T/pip_build_kim/lxml/src/lxml/includes -I/usr/local/Cellar/python/2.7.7_1/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c src/lxml/lxml.etree.c -o build/temp.macosx-10.10-x86_64-2.7/src/lxml/lxml.etree.o -w -flat_namespace

我的解决方案就是 copy 一个副本到安装目录
