Acts as ferret not working in dev


I have acts as ferret working ok on the production server with the built
in drb server.

Locally i can get the server running ok but get the following errors
when trying to run a search within an app

undefined method find_with_ferret' for #<Class:0x2f4c3e0> undefined methodferret_rank=’ for #Product:0x302643c

Using the console the search actually returns the expected the results
which is baffling me a bit. So
Product.find_with_ferret(‘test’) will work in the console but not in the

I have the same version of ferret locally as i do on the production
I can rebuild the indexes ok.
The indexes i have are sharedindex, see below,

:models => {
Product => {:fields => [:name, :desc, :meta_keywords, :meta_desc,
:manufacturer_name],:remote => true},
HostApplication => {:fields => [:name, :desc, :meta_keywords,
:meta_desc], :remote => true},
Manufacturer => {:fields => [:name, :desc, :meta_keywords,
:meta_desc], :remote => true},
Category => {:fields => [:name, :desc, :meta_keywords, :meta_desc],
:remote => true}

Has anybody got any ideas whats wrong? Ive searched around google with
no joy. My dev env is mac, ruby 1.8.7, Rails 2.3.2,
