Needs a checking that lxml and libxml2 are installed

[iampbernardo]

During installation with pip, you can get an error because lxml and libxml2 are not installed. I installed equivalent packages, but looks like python-lxml could make the trick.

lxml is a package dependency on setup.py. How this could happend? Did you have the output error?

[iampbernardo]

I had some other problems with my machine. Let me try this again with the fresh install I made today and will tell you everything goes ok.
