Installing python newspaper on El Capitan

I've beeing struggling to install newspaper library on El Capitan. Finally found a command with which it would install without any issues.

sudo STATIC_DEPS=true pip install newspaper --ignore-installed six

Errors which I was getting, for lxml:

and for six module:

  Found existing installation: six 1.4.1

    DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
