and 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 doing wrong. suggestions?

finally got it. had uninstall rails 2.3.8 , rack 1.1 , install rails 2.3.5 , rack 1.0.1 guess version of ironruby i'm running (1.0) has issues newer version of rails. anyways worked after did that.
