Mac OS X Leopard?

I was in the Apple store thinking about buying a new computer. I've
never owned Mac before, and I stumped the folks there by asking if it
would run Adom. We downloaded and installed Adom, but it gave some
sort of exception error (wish I could provide the details). I had two
or three of the employees trying to sort out the problem.

We did follow the directions at adom.de, i.e., setting the term color
and so on.

The application wouldn't even run, providing a very verbose error
involving thread exceptions (if I can recall correctly).

Has anyone successfully run Adom on the new Mac OS? I'd rather not buy
a computer, only to have to buy a copy of Windows for dual-boot just
to run my roguelikes.
