I did report that to Stefan V. in IRC via #sage-devel and I also thought that this was still a problem with numpy 1.1.0, but fortuantely that was fixed.

Sage needs it for twisted, so it isn't an option. I will clean up my fix and post it to the python list soon [I have been busy with $WORK, so no clean version yet], but if anybody cares here I can post a simple step by step workaround. The issue here is that the libffi used by ctypes is way out of date and as is does not have 64 bit OSX support. Hope this helps. Congratulations on numpy 1.1.0 - I mostly lurk here, so I didn't have a chance yet.
