Ever since Leopard, Apple sets DISPLAY for you, to a special value that makes automatically anytime it's needed. If you override DISPLAY and set it to something like ":0" then will no longer automatically launch when needed, and you'll have to launch it manually.

It is possible that python-xlib does not like this special value Apple uses for DISPLAY. What problem do you see when you don't override DISPLAY?
