GCC错误:命令"gcc-4.0"失败，退出状态为1

我正在尝试将Fabric安装到具有Xcode 4.2的Virtualenv/Django 1.3.1/OS X Lion中.此错误似乎是相当普遍的，但我不能您在运行python 2.7&时似乎找到了答案. Xcode 4.2.

I am trying to install Fabric into a Virtualenv / Django 1.3.1 / OS X Lion with Xcode 4.2. This error seems to be fairly prevalent but I can't seem to find an answer when you are running Python 2.7 & Xcode 4.2.

我正在跑步:

Python 2.7(r27:82508，2010年7月3日，21:12:11) [GCC 4.0.1(Apple Inc.内部版本5493)]

Python 2.7 (r27:82508, Jul 3 2010, 21:12:11) [GCC 4.0.1 (Apple Inc. build 5493)]

如何执行gcc-4.0而不是gcc-4.0.1?

How do I execute gcc-4.0 instead of gcc-4.0.1?

谢谢！
