That is what I expected. Perhaps it is a matter of changing some setting
in the uncompression tool? The Mac (a G5 iMac) is at home so I will have
to look into this later.

I thought you guys might have been using Xcode 3.0 already - I doubt
there would be any real difference between 2.0 and 2.3. My problem was
very likely to have been in the uncompression stage.

Thanks! Though as you mentioned below, I probably don't actually need
it. But it might be nice to have in case I do want to run stuff in the
future, so first I will try to fix that bundle/folder thing. If that
doesn't work then it would be great to get the pre-compiled debug server
for the PowerPC.

I got dumped into the VM# prompt and didn't try restarting the scheduler
(and then the desktop) to see what would happen. I'll have to run it
again to see what the errors were.

It looked like all the files had been read in and there were lots and
lots of tests sending their output to the console, each one related to a
PowerPC instruction (I think - it has been a looong time since I looked
at that processor's instruction set). I will try "prompt start" and
"desktop go" (just looked these up ;-) if I get another crash.
One thing I am interested in is comparing Klein with the sources for
Exupery, which is a bytecode-to-x86 compiler written in Squeak
Smalltalk. The goals are rather different (the focus for Exupery is good
code generation at the cost of compilation speed) so I want to see what
effect, if any, that had on the program structure.
