<<-EOS.undent
Your default Python does not recognize the Homebrew site-packages
directory as a special site-packages directory, which means that .pth
files will not be followed. This means you will not be able to import
some modules after installing them with Homebrew, like wxpython. To fix
this for the current user, you can run:
mkdir -p #{user_site_packages}
echo 'import site; site.addsitedir("#{homebrew_site_packages}")' >> #{user_site_packages}/homebrew.pth
