Summary

Some of the vendored libraries, e.g. rope and pylama, depend on pkg_resources, but pkg_resources itself is not vendored. Should it be vendored as well?

Background

I'm setting up python-mode using home-manager. home-manager is a package manager that installs neovim, python, etc. To keep it brief, home-manager is very careful about dependencies and the python environment that it sets up for python-mode does not include pkg-resources. So I'm wondering if this should be fixed in python-mode or elsewhere, in the code that creates the Python environment that python-mode uses.
