Will_paginate & vote_fu

Hola, estamos intentando incluir un sistema de votaciones para los
videos de nuestra web. Para ello hemos incluido el plugin vote_fu

GitHub - peteonrails/vote_fu: Vote and Karma Management.

Instalamos el plugin y realizamos la migracion:

== 20090324090130 VoteFuMigration: migrating

– create_table(:votes, {:force=>true})
→ 0.0801s
– add_index(:votes, [“voter_id”, “voter_type”], {:name=>“fk_voters”})
→ 0.0404s
– add_index(:votes, [“voteable_id”, “voteable_type”],
{:name=>“fk_voteables”})
→ 0.0359s
== 20090324090130 VoteFuMigration: migrated (0.1569s)

Queremso qeu los usuarios puedan votar los videos:

class Video < ActiveRecord::Base
acts_as_voteable
end

class Usuario < ActiveRecord::Base
acts_as_voter
end

Cuando intento arrancar el localhost, tan solo habiendo escrito el
codigo de arriba me sale el siguiente error:

NameError (undefined local variable or method acts_as_voter' for #<Class:0x33623bc>): /opt/local/lib/ruby/gems/1.8/gems/activerecord-2.1.2/lib/active_record/base.rb:1672:in method_missing_without_paginate’

He intentado buscar por google, pero tan solo he podido encontrar a un
brasileño en el google talks que le sucedia lo mismo. Alguien ha
implementado este plugin junto al will paginate con exito??. Cualquier
ayuda sera agradecida.

Un saludo

Parece que era cosa de reiniciar el servidor, ahora ya no sale ningun
error.
