Ok, I got the Rails webapp working... The main 'trick' is that the working directory has to be .../Web Interface, or the RAILS_HOME variable ends up not being set correctly. So, two steps:

1) cd ~/Library/Application\ Support/OmniFocus/Web\ Interface
2) ./script/server

If you've never done this before, this _won't_ work, you need to also edit Settings.plist, and minimally replace YOUR_PASSWORD and YOUR_USERNAME with the values you wish to use. None of the app is accessible without authenticating.
