Rails Big Blue Button

Is there any stable version for Big blue button on rails 3 ?

I am using http://ift.tt/1MxoRX0 for rails and I started getting errors. Although I have fixed few but I got struck in the following error which is related to I18n. Suggest me necessary changes.

ArgumentError in Bigbluebutton::RoomsController#join

uncaught throw :exception Rails.root: /home/cnt/rails_proje/begalileo
