A "distutils.cfg" has been written to:
#{distutils}
specifying the install-scripts folder as:
#{scripts_folder}
If you install Python packages via "pypy setup.py install", easy_install_pypy,
or pip_pypy, any provided scripts will go into the install-scripts folder
above, so you may want to add it to your PATH *after* #{HOMEBREW_PREFIX}/bin
so you don't overwrite tools from CPython.
Setuptools and pip have been installed, so you can use easy_install_pypy and
pip_pypy.
To update setuptools and pip between pypy releases, run:
pip_pypy install --upgrade pip setuptools
See: https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/Homebrew-and-Python.md
