I finally got around to cleaning up my Ruby filetype plugin for the Vim 
editor.

With it, you can:

* use matchit.vim for navigating between if/else/end, def/end, etc. pairs 
using the % key
* use gf [i [I [d [D etc. to navigate and search
* use tags even if you use identifiers with :: in them
* have a properly set include path automatically

You can get it at http://bike-nomad.com/vim/ruby.vim
