Curses.Blinkenlights not working on Mac OS X

[Adeel Ahmad Khan]

I get an error when trying to run offlineimap with Curses.Blinkenlights:

Thread 'InputHandler loop' terminated with exception:
Traceback (most recent call last):

No debug messages were logged for InputHandler loop.

Is there any way to make this UI work on Mac OS X?  (10.6.4)
