我正在尝试安装 numpy，以便之后可以安装 biopython。我已经安装了 pyton 2.7，当我在命令提示符下键入 python 时，我得到以下信息：
python
Python 2.7.4 (v2.7.4:026ee0057e2d, Apr 6 2013, 10:15:50)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
所以我确实有C编译器。现在，当我下载 numpy 的 .tar 并执行以下步骤时：
> tar -xzvpf numpy-1.5.1.tar.gz
> cd numpy-1.5.1/
> python setup.py build
我收到以下错误：
