Python/Pillow无法安装在MacosxMavericks上

Question

最近我把我的系统升级到MacOSX 10.9.4。我的整个开发环境现在一团糟。我正在尝试重新安装或恢复模块、库，甚至一些应用程序。在

我使用的是Django1.6，我的一个模型中有ImageField，这当然需要安装PIL或枕头。但我无法安装Pillow，原因是以下警告：

我四处寻找，找到了几个解决办法，但对我没用。现在，当我试着做brew install pillow时，它说pillow2.5.1 already install, it's just not linked。请注意，我最近使用了这个解决方案： https://stackoverflow.com/a/22651557/878170

我怎样才能解决这个问题？在
