Do you have an ADC account? If so, could you please file a bug at bugreport.apple.com? That way there is at least a small chance that this bug gets fixed in a future release of OSX (and that someone that actually cares about this gets notified when Apple says it has fixed this issue).

If you install your version of readline as an egg (through setuptools) it will be earlier in sys.path than the system version of readline. Alternatively you can use a pth-file that inserts the directory with your copy of readline.so early in sys.path.
