【问题描述】：
我正在尝试在运行 Python 2.6 的 Ubuntu 服务器上安装 lxml（在 virtualenv 中 - 系统 Python 为 2.5）。
我已经通过 svn 签出，结果我还安装了 Cython，as per the instructions。
但是，运行python setup.py build 时出现以下错误：
Building lxml version 2.3.alpha1-76211.
Building with Cython 0.11.
Using build configuration of libxslt 1.1.22
Building against libxml2/libxslt in the following directory: /usr/lib
running build
running build_py
running build_ext

for i in range(c_tag_count):
if _tagMatchesExactly(c_child, c_ns_tags[2*i], c_ns_tags[2*i+1]):
c_next = _findChildForwards(c_child, 0) or _nextElement(c_child)

src/lxml/lxml.etree.c:1:2: error: #error Do not use this file, it is the result of a failed Cython compilation.
error: command 'gcc' failed with exit status 1
如果我尝试python setup.py bdist_egg、python setup.py build_ext -i 或make，则会出现非常相似的错误
尝试通过 easy_install 或 pip 安装会产生相同的错误 - 尽管前者只是无限期挂起。
据我所知，所有各种依赖项都已安装，例如 python-dev。
我错过了什么/做错了什么？
