Good Afternoon,

I recently bought a new imac and decided to give RoR a try. OS X comes  
standard with it, but in “Agile Web Dev with Rails” it suggested I may  
want to update. Well, after updating, I can’t get anything to work. I  
accidentally ran:

```auto
gem update --system

```

I think this threw my system off. Is there a way to revert rails, ruby  
and ruby gems? Any suggestions would be helpful.

Here is one error I am getting:
