I use Buildout: http://docs.buildout.org/en/latest/ http://docs.buildout.org/en/latest/ Buildout is much more than a Python package manager. It runs pluggable recipes, where building/installing a Python package is only one of the many available recipes. It was invented at a company where I once worked. It replaced huge piles of complicated Makefiles. Buildout is obviously less popular than other solutions, but I think it manages complexity quite well and saves me a lot of time compared with other ways I could assemble Python software.
