    For non-homebrew Python, you need to amend your PYTHONPATH like so:
      export PYTHONPATH=#{HOMEBREW_PREFIX}/lib/#{which_python}/site-packages:$PYTHONPATH
    EOS
  end

  def which_python
    "python" + `python -c 'import sys;print(sys.version[:3])'`.strip
  end

  test do
    system "python", "-c", "import gtksourceview2"
  end
