Greetings. I just started a new rails project basing off the edge.[1](http://ariejan.net/2009/01/04/how-to-start-a-rails-edge-app-the-easy-way/)  
I prefer to unpack my gems, but when I did so, I received the error  
below. Anybody else encounter this and have a suggestion?

$ rake gems:unpack  
(in [omitted])  
rake aborted!  
undefined method `rescue\_responses’ for ActionController::Base:Class

(See full trace by running task with --trace)

## Thanks, Ben
