pls help, thanks!

i have in config.ru file

require './app' require 'sinatra/activerecord/rake'  run sinatra::application

i tried same config.ru. when removed

require 'sinatra/activerecord/rake'

everything started work.

method "namespace" defined in rake/dsl_definition.rb. so, application extending sinatra::base doesn't see it.
