Thank you very much for your time an explanations.
It looks like by switching to JRuby one would actually gain functionalities.
Also, since at the moment I don't have any truly number crunching appls
which would really benefit from a faster Ruby, I would give JRuby a try this
weekend.
I guess I would have to uninstall Ruby. That's not a big deal!

Again, thank you for your time and consideration.

Victor
