gcc: _mssql.c: 没有这个文件或目录

Question

我正在尝试为 Python 2.5 编译 pymssql。我这么做是因为我觉得我现在的 pymssql 版本是为 Python 2.4 编译的。这个错误让我觉得是这样：

/home/username/lib/python2.5/pymssql.py:30: RuntimeWarning: Python C API version mismatch for module _mssql: This Python has API version 1013, module _mssql has version 1012.
import _mssql

无论如何，我在使用 Ubuntu 10.10，并通过 deadsnakes ppa 安装了 python2.5 和 python2.5-dev。我创建了一个使用 python2.5 的虚拟环境，方法是：

mkvirtualenv pymssql -p /usr/bin/python2.5

我通过 pip 安装了 cython，现在想通过 pip 安装 pymssql，但遇到了这个错误：

有没有什么办法可以解决这个问题？
