I think that what Luis was trying to say is that Ruby 1.9 is not backwards-compatible with Ruby 1.8, and for that reason a number of gems that work with Ruby 1.8 don't yet work with Ruby 1.9. As far as I know, the best resource for checking this out (other than your own experimentation) is the web site: http://isitruby19.com/ If a particular gem that you need isn't working under Ruby 1.9 yet, you might try contacting the developer(s) for that gem to see what's up. Hope this helps, Lyle
