A "distutils.cfg" has been written to:
#{distutils}
specifing the install-scripts folder as:
#{scripts_folder}
If you install Python packages via "pypy setup.py install", easy_install_pypy,
pip_pypy, any provided scripts will go into the install-scripts folder above,
so you may want to add it to your PATH *after* the `$(brew --prefix)/bin`
so you don't overwrite tools from CPython.
Setuptools has been installed, so easy_install is available.
To update setuptools itself outside of Homebrew:
#{scripts_folder}/easy_install pip
#{scripts_folder}/pip install --upgrade setuptools
See: https://github.com/Homebrew/homebrew/wiki/Homebrew-and-Python
