As far as I am concerned this contains about anything you need to
know. Are you missing something specific?

This is the platform Ruby was built for, seems to be OS-X.
But the VERSION and PATCHLEVEL is more important concerning the
"behavior" of the interpreter or VM. In your case MRI with a quite
recent patchlevel. Congrats ;)
This, however is a more conservative Ruby version. You might want
1.8.7 or 1.9.1 for exploration.

Remark that JRuby uses "java" as a platform. This is surely to
indicate that it will run wherever Java runs.
