Distribute and Pip have been installed. To update them
pip install --upgrade distribute
pip install --upgrade pip
To symlink "Idle" and the "Python Launcher" to ~/Applications
`brew linkapps`
You can install Python packages with (the outdated easy_install or)
`pip install <your_favorite_package>`
They will install into the site-package directory
#{site_packages}
Executable python scripts will be put in:
#{scripts_folder}
so you may want to put "#{scripts_folder}" in your PATH, too.
