GCC 错误：命令“gcc-4.0”失败，退出状态为 1

我正在尝试使用 Xcode 4.2 将 Fabric 安装到 Virtualenv / Django 1.3.1 / OS X Lion 中。这个错误似乎是相当普遍 https://stackoverflow.com/questions/6906385/mac-osx-lion-virtualenv-pil-install-gcc-error但当你运行 Python 2.7 和 Xcode 4.2 时，我似乎找不到答案。

我在跑：

Python 2.7（r27:82508，2010 年 7 月 3 日，21:12:11） [GCC 4.0.1（苹果公司内部版本 5493）]

如何执行 gcc-4.0 而不是 gcc-4.0.1？

Thanks!

完整的 Fabric 安装 + 错误：

OSX 10.7 也有同样的问题。我的修复：

cd /usr/bin
sudo ln -s gcc gcc-4.0

我下载的 MySQL-python 版本名为 gcc-4.0 gcc 已经是 apple gcc 版本的符号链接。

附：确保您还安装了 xcode 和命令行工具
