Accessing FB Graph API using Ruby 1.8 and Rails

I'm adding Facebook functionality on to a开发者_开发知识库 site running Ruby 1.8.6 and rails 1.2.3.

Are there any gems that will let me use facebook's graph api with these versions?

Check out Koala - https://github.com/arsduo/koala/wiki Really a solid gem. Wait, Rails 1.2.3? Did I read it right?
