-      This formula installs PIL against whatever Python is first in your path.
-      This Python needs to have either setuptools or distribute installed or the

-      If you are using a Homebrew-built Python, you can do:
-        brew install distribute
-      to get this support library.

-      If you are using a custom Python, run:
-        brew info distribute
-      to see manual setup instructions.
