I use that setup on one of the machines, too.
Should not be problem with the 32bit libraries.

Pharo works currently only with a single core, I think.
And there might be one of my latest fixes missing in the current change set for Pharo.
The event processing is broken somehow. I have a work-around (below) but still need to figure out why the eventBuffer is not filled in correctly by the primitive.

Wouldn't be surprised if it is again Pharo's compiler *grml*. The other forks work, so I doubt that it is the primitive/VM.
