Do not report this issue to Homebrew/brew or Homebrew/core!

Are there any prerequisites I'm missing? Searching for the particular error lead to suggestions of globally installing setuptools, but if I'm reading the history above correctly, it's doing that at the start (my python isn't my strongest language), and generally isn't a good idea anyway.
