Error installing python module lxml on osx mavericks

Here is my python env: note that numpy is working

13:41:44/shared:5 $python
Python 2.7.5 (default, Aug 25 2013, 00:04:04)
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from numpy import *
>>> print mat([1,2,3])
[[1, 2, 3]]
>>>

But I am unable to install lxml. What is missing in my python and/or os configuration to make this work:

13:37:03/shared:4 $pip install --upgrade lxml

It seems like you are missing libxml/xmlversion.h

Since it seems that /usr/include/libxml2 is being included, I think the most probable reason is that you don't have libxml2 installed on your system. This is most likely due to missing "command line tools". Get them here: https://developer.apple.com/downloads/index.action?=command%20line%20tools

Can also be solved by installing libxml2 via macports or brew (But don't do this other than as last resort). Using system libraries instead of homebrew or macports whenever possible can save you from a lot of incompatibility pitfalls.
