I ran into [this problem](https://stackoverflow.com/questions/7648200/pip-install-pil-e-tickets-1-no-jpeg-png-support) but on OS X instead of Ubuntu. I figured out the fix on OS X, but the solution is different because it involves installing appropriate dependencies. 

I'd like to document the OS X solution. Should I add a new answer to this question, or open a new question that is specific to OS X?
