gem error wont let mongrel start

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: [code=]C:\InstantRails\rails_apps\contrastream>ruby script/server => Booting Mongrel (use 'script/server webrick' to force WEBrick) => Rails application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server ** Starting Mongrel listening at 0.0.0.0:3000 ** Starting Rails with development environment...

Anyone having any ideas? I'm completely lost on this one..
