无法在Mac Mavericks上安装Python MySQL库
在更新了Mountain Lion之前，一切都运行得很好。
但更新之后，它就坏了，我无法再让环境正常工作。
有没有人知道怎么修复这个问题？
下面是错误信息，已经加粗了。

更新：
按照建议，我添加了：
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
但是这导致错误变成了：
error: /Library/Python/2.7/site-packages/_mysql.so: Permission denied
我刚把这个目录的权限改成可以写入，然后就好了 :)
这都是因为我把macports、easy_install和pip搞混了……真是丢脸。

在Ned的回答基础上：
因为我不想用sudo来安装软件包（我在使用虚拟环境），也不想影响我的全局环境，所以我在一次性执行的pip install命令中添加了两个变量：
CFLAGS=-Qunused-arguments CPPFLAGS=-Qunused-arguments pip install -r requirements.txt

这个问题是因为Xcode 5.1版本做了一些改动，还有苹果自带的系统Python 2.7的构建方式导致的。在运行pip之前，试着添加这些环境变量的值：
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
想了解更多信息，可以查看这个链接：clang错误：未知参数：'-mno-fused-madd'（Python包安装失败）。
更新 [2014-05-16]：果然，苹果在OS X 10.9.3中更新了系统Python（2.7、2.6和2.5），解决了这个问题，所以在使用最新的Mavericks和Xcode 5.1+时，不再需要这个临时解决办法。不过，目前在OS X 10.8.x（山狮，目前是10.8.5）上，如果你使用Xcode 5.1+，还是需要这个临时解决办法。
