I had a crack at this and got quite warm, literally and metaphorically.
But, no, I didn't quite get there. And yes, it's some sort of libraries
issue. Here's the barf...

...which makes me wonder just what I need to delete.

This sort of issue is beyond my ken, but I'm willing to learn.

I also have no especial attachment to Leopard.

Clues appreciated
