Looks like Tim Bray has wrapped up the Ruby Ape Diaries. In that latest post he points out a few things Ruby needs, one of which is an IDE.

I’m using the RDT eclipse plugin. It is pretty good, as good as I’ve found anyway. It does have syntax highlighting, content assist, an outline for Class navigation, and a Unit Test launcher which uses the same unit test runner as the JDT(java development tools). As far as I know it doesn’t have any refactoring support.

And, IIRC, it’s built on JRuby.

There is an introductory article to the tool at IBM developer works.

There is also a Rails plugin, Rad Rails, which I know absolutely nothing about.
