I am trying to use exception_notification but I get this error:

I followed this tutorial and the tutorial on github:

That repo has been updated for Rails 3, so it's going to fail badly on
older versions. You'll probably want to grab only up to this commit:

http://github.com/rails/exception_notification/commit/e8b603e523c14f145da7b3a1729f5cc06eba2dd1

Or you may want to look into another exception notifier, like Hoptoad.
