IronRuby on Rails with IIS 7

Question

I'm trying to get a Rails app built with IronRuby running on IIS 7. I followed all the tutorial given on the IronRuby site but I can't seem to get it to work. The app runs fine hosted under WebBrick but IIS doesn't seem to host it properly. Here is the page I get.

Error: exit

and my config.ru file

# RAILS_ROOT/config.ru
require "config/environment"

ENV['RAILS_ENV'] = 'development'

use Rails::Rack::LogTailer
use Rails::Rack::Static
run ActionController::Dispatcher.new

I'm not sure what I am doing wrong. Any suggestions?

Finally got it. I had to uninstall Rails 2.3.8 and Rack 1.1 and install Rails 2.3.5 and Rack 1.0.1 I guess the version of IronRuby I'm running (1.0) has issues with the newer version of rails. Anyways It worked after I did that.
