That's happening because the 'pep8' target is installing all the
requirements for the project in a virtualenv, and one of them needs
Python development headers. What Linux distro are you using? On Fedora
you can fix this like so:

    sudo dnf install python-devel

On Ubuntu, I think it's something like this:

    sudo apt-get install python-dev
