A "distutils.cfg" has been written to:

specifing the install-scripts folder as:
#{scripts_folder}
If you install Python packages via "pip install x" or "python setup.py install"
(or the outdated easy_install), any provided scripts will go into the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. To update distribute itself outside of Homebrew:
#{scripts_folder}/pip install --upgrade distribute
