* Added as a formula because installing using pip does not pick up
  many optional but useful dependencies.

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