我在CentOS 5.4上安装了Python 2.6.6，
[siyuan.tong@SC-055 lxml-2.3beta1]$ python Python 2.6.6 (r266:84292,Jan 4 2011,09:49:55) [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2 Type "help","copyright","credits" or "license" for more information. >>>
我想使用lxml模块，但从源代码构建失败：
src/lxml/lxml.etree.c:157929: error: ‘xsltLibxsltVersion’ undeclared (first use in this function) src/lxml/lxml.etree.c:157941: error: ‘__pyx_v_4lxml_5etree_XSLT_DOC_DEFAULT_LOADER’ undeclared (first use in this function) src/lxml/lxml.etree.c:157941: error: ‘xsltDocDefaultLoader’ undeclared (first use in this function) src/lxml/lxml.etree.c:157950: error: ‘__pyx_f_4lxml_5etree__xslt_doc_loader’ undeclared (first use in this function) error: command 'gcc' Failed with exit status 1
我有同样的问题，我管理安装软件包libxslt-devel和python-devel似乎是你的问题后安装它：
yum install libxslt-devel python-devel
python setup.py安装
Installed /usr/lib/python2.6/site-packages/lxml-2.2.8-py2.6-linux-i686.egg Processing dependencies for lxml==2.2.8 Finished processing dependencies for lxml==2.2.8
但是，由于我也安装了其他软件包在进程中，你可能要双重检查libxml2，libxml2-devel和libxslt，而你在它。
这里是一些关于如何建立lxml：http://lxml.de/build.html的信息
