安装pylibmc OSX 10.9时遇到问题

Question

我用自制软件安装了libmemcached，并尝试用PIP安装pylibmc，但没有成功：

Downloading/unpacking pylibmc==1.2.2
  Running setup.py egg_info for package pylibmc

我找到了这个链接-http://sendapatch.se/projects/pylibmc/install.html#requirements，但不确定应该把什么作为LIBMEMCACHED路径-正如我通过自制程序安装的那样-我尝试了一些路径，但是所有路径都给出了与上面相同的错误。在
