Problem starting servers with acts_as_ferret

Hello

I’m having a problem with starting both Mongrel in Aptana Studio
(RadRails). The following happens:

** Starting Mongrel listening at 0.0.0.0:3001
** Starting Rails with development environment…
c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in

require' from ./script/server:3 from -e:2:inload’
from -e:2

The exact same problem happens with WEBrick too.

Has anyone come across this issue before? I have the acts_as_ferret
plugin installed fine.

Any help appreciated.

Cheers
