Python 在Mac OS X Mavericks上安装gevent时出现问题

我在Mac OS X Mavericks上安装gevent时遇到了问题。我正在尝试安装到虚拟环境中。首先，我用brew安装了libevent。然后我跑：

pip install gevent

很遗憾，我无法安装它，因为我一直收到以下错误消息：

Command /Users/christopherspears/.virtualenvs/traffic/bin/python -c "import setuptools, tokenize;__file__='/Users/christopherspears/.virtualenvs/traffic/build/greenlet/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /var/folders/yv/vnky4wpd7kl4bp4qb4hlqmhw0000gn/T/pip-91tw1E-record/install-record.txt --single-version-externally-managed --compile --install-headers /Users/christopherspears/.virtualenvs/traffic/include/site/python2.7 failed with error code 1 in /Users/christopherspears/.virtualenvs/traffic/build/greenlet
Storing debug log for failure in /Users/christopherspears/.pip/pip.log

问题似乎出在greenlet身上。还有其他人遇到过这个错误吗？

你看过/Users/christopherspears/.pip/pip.log的内容了吗？
