A "distutils.cfg" has been written, specifying the install-scripts directory as:

If you install Python packages via "pip-3.2 install x" or "python3 setup.py install"
(or the outdated easy_install3), any provided scripts will go into the
install-scripts folder above, so you may want to add it to your PATH.
The site-package directory for brewed Python:

Distribute and Pip have been installed. To update them:
#{scripts_folder}/pip-3.2 install --upgrade distribute
#{scripts_folder}/pip-3.2 install --upgrade pip
