Jim, I'm competent only to comment on part of your problem. I know this: 
If you have Ruby 1.8.x installed, and then also install 1.9.x, the 
installation process will keep them separate by appending ...1.9 to all 
(I HOPE all!) the 1.9 components. That's what happened on my Kubuntu 
Linux OS. What implications this might have for the internals of various 
Ruby scripts of which any particular piece of software s composed I can 
only conjecture.

I think you may have two Ruby's installed on your OS. For the present, I 
don't think there's a realistic alternative to this setup. I'm NOT sure 
how best to manage it, however. Still learning.
