I ran into the same problem independently on an Intel Mac (I didn't read these messages until now) and came up with the first part of Jae-Joon Lee's fix. It does fix the problem, at least for me - I suspect the difference may not actually be in the platform but in the exact version of numpy (I have 1.1.0). I also committed the other part of the fix.
This does seem to fix the problem, but I think we should wait for confirmation from John before releasing the code. -- Jouni K.
