[self-interest] Corrupt Clear.snap and demo.snap on Leopard

I'm not sure what the issue is, but since you are on PPC, possibly something has gone wrong with the mechanism for saving generated machine code in the snapshot (which was built on x86)


> self -F -s /library/self/0/Demo-4.4.snap

which attempts to load while abandoning any included machine code. 

Otherwise, I suggest cloning the github tree, going to the objects directory and building a new snapshot from source:

> self -f worldBuilder.self

(then "desktop open" to start the GUI)

Cheers, Russell
