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:

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