can't installing lxml on Ubuntu 12.04

Question

I've been trying to install lxml using pip install lxml and I get the error below. I've used apt-get install python-dev libxml2 libxml2-dev libxslt-dev before (suggested in other answers) but I still get the same error. I did not use control-c.

Try this to get the deps:

apt-get build-dep python-lxml
