Carriles - motor de Liquidación - problema de instalación

Question

La instalación para el despacho parece muy sencillo ( https://github.com/thoughtbot/clearance). Estoy siguiendo las instrucciones que, a pesar de que estoy recibiendo un error casi inmediatamente.

Por la etapa quinta "rake db: migrate"

Me sale el siguiente error:

rake aborted!
undefined method `configure' for Clearance:Module

No tengo ni idea de lo que debería estar haciendo de manera diferente?

Gracias de antemano!

** Invoke db:migrate (first_time)

** Execute environment

Ahora resulta que el wiki de la instalación era anticuado. Desde entonces se ha actualizado.
