What version of python is this?  Based on the naked "print" I guess
2.x, and I got:

$ /opt/python2/bin/python2.7
Python 2.7.2 (default, Oct 10 2011, 03:43:34)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import lxml.html
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named lxml.html
