A "distutils.cfg" has been written to:
#{lib}/pypy/distutils
specifing the install-scripts folder as:
#{scripts_folder}
If you install Python packages via "pypy setup.py install", easy_install, pip,
any provided scripts will go into the install-scripts folder above, so you may
want to add it to your PATH.
Distribute has been installed, so easy_install is available.
To update distribute itself outside of Homebrew:
#{scripts_folder}/easy_install pip
#{scripts_folder}/pip install --upgrade distribute
