Compiling and testing lxml2..

The instructions for recompiling lxml seem pretty straightforward. You have to pip install Cython, which is used to convert the .pyx file into a .c file, which then can be gcc compiled. The libxml2-dev and libxslt-dev must be packaged installed.

http://lxml.de/1.3/build.html

git clone https://github.com/lxml/lxml/
sudo apt-get install libxml-dev
sudo apt-get install libxslt-dev
pip install Cython
python setup.py build_ext

If you want to test that the unit tests still pass, you can link the uld type:

cd src/lxml
ln -s ../../build/lib.linux-x86_64-2.6/lxml/etree.so 
cd ../..
python test.py test_etree.py
