Good news

I've finished setting up my new desktop machine, and I've managed to compile Tart and run all of the tests - which passed.

So the overall status looks like this:

• 64-bit Linux (Ubuntu): Pass
• 64-bit OS X (Snow Leopard): Pass
• 32-bit OS X (Leopard): Fail

That's all the data points I have at the moment, but it'd a good bet that the problem has to do with 64 vs. 32 bit compatibility.
