Unix dependencies

[lucidsushi]

What would the setup.py look like for packages that rely on certain linux packages to also be installed via apt-get/yum/brew ?

my advice: document the dependencies but don't do anything in the installation to install them.

You don't know the context in which your python package will be installed, even if you check the OS. Your package might be part of a docker image, which would have such dependencies installed in another layer or copied from another image.
