mongrel --prefix does not properly notify rails 2.1.1

As of Rails 2.1.1, ActionController::AbstractRequest.relative_url_root no longer exists. It has been replaced by ActionController::Base.relative_url_root. This allows you to run your rails app in a virtual sub-directory of your webserver. The mongrel rails handler uses this method to set the relative url for your rails app. When working properly, mongrel_rails start --prefix /app would result in rails automatically generating URLs like http://somedomain/app/action.

Currently in mongrel 1.1.5 and Rails 2.1.1, if you wish to have this functionality you must set the relative_url_root by hand somewhere in your environment like so: 
ActionController::Base.relative_url_root = "/app" if 'production' == ENV['RAILS_ENV']
I have submitted a patch to mongrel, but if you can’t wait for the new release of mongrel, here is the patch:
