我在Ubuntu 11上使用easy_install安装lxml有困难。
当我输入$ easy_install lxml时，我得到:

ERROR: /bin/sh: xslt-config: not found
** make sure the development packages of libxml2 and libxslt are installed **
Using build configuration of libxslt

似乎没有安装libxslt或libxml2。我试着按照http://www.techsww.com/tutorials/libraries/libxslt/installation/installing_libxslt_on_ubuntu_linux.php和http://www.techsww.com/tutorials/libraries/libxml/installation/installing_libxml_on_ubuntu_linux.php上的说明操作，但没有成功。
如果我试着wget ftp://xmlsoft.org/libxml2/libxml2-sources-2.6.27.tar.gz我得到
<successful connection info>
==> SYST ... done. ==> PWD ... done.
==> TYPE I ... done. ==> CWD (1) /libxml2 ... done.
==> SIZE libxml2-sources-2.6.27.tar.gz ... done.
==> PASV ... done. ==> RETR libxml2-sources-2.6.27.tar.gz ...
No such file `libxml2-sources-2.6.27.tar.gz'.
如果我先尝试另一个，我会得到。/configure——prefix=/usr/local/libxslt——with-libxml-prefix=/usr/local/libxml2，最终会失败:
checking for libxml libraries >= 2.6.27... configure: error: Could not find libxml2 anywhere, check ftp://xmlsoft.org/.
我尝试了libxml2的2.6.27和2.6.29两个版本，没有什么不同。
不遗余力，我已经成功地完成了sudo apt-get安装libxml2-dev，但这没有改变什么。
