It's closer to the first since it's a non-Apple version and there's only one arch that can be executed (I'm not even going to think about trying to get a ppc running through Rosetta!). It resembles the second since it looks like some 64-bit attempts need to be back tracked. > I spent a lot of time getting it to run on my Snow Leopard install.
