Fix

Open

C:\ruby\lib\ruby\gems\1.8\gems\opensocial-0.0.4\lib\opensocial\auth\action_controller_request.rb

and resplace "proxies ActionController::AbstractRequest" with "proxies ActionController::Request" at Line 32
or more specifically

module OAuth::RequestProxy #:nodoc: all
  class ActionControllerRequest < OAuth::RequestProxy::Base
    # proxies ActionController::AbstractRequest
    if ActionController.const_defined?(:AbstractRequest)
      proxies ActionController::AbstractRequest
    else
      proxies ActionController::Request
    end
  #...
  #...
end
