Am I Ruby 1.9?

Kevin and I were chatting about how to tell if your locally installed gems were compatible with Ruby 1.9. He was looking for a tool that would scan the list and figure out which ones worked. I pointed him to Is It Ruby 1.9?, he found the API and whipped up a gem that would tell you which of your gems would likely work (or not work) with the latest version of Ruby. Check it out:

$ sudo gem install n3bulous-amiruby19 --source=http://gems.github.com

Then let it loose on your system:

$ amiruby19

Oh, and it was built with simple-gem (shameless plug).
