This. Right here. All these small necessary evils are nothing compared to bigger pains. From the top of my head. I'd kill to have a Gemfile scheme that's actually used by everybody. We could emulate this pretty darn closely with setup.py and requirements.txt (for Gemfile and Gemfile.lock, respectively). But, most of us just don't. Tox generally makes matters worse (since it promotes people dropping even more untracked deps in there), even though it's a great tools for what it was designed.
