I’m getting a really confusing error which I have no idea how to fix,  
its happens when mongrel loads gems

it happened after I installed act\_as\_ferret gem. I’ve since deleted  
the gem and reinstalled ruby completely. After deleting ferret I get  
the same error on my savage beast plugin. The issue is with my app  
since mephisto loads fine on a separate instance.

error:

Anyone having any ideas? I’m completely lost on this one…
