Authlogic lanza errores en Heroku

Question

Estoy tratando de organizar una aplicación en Heroku que utiliza el plugin Authlogic. Los registros de este error me muestran. Al principio pensé que hay un problema con la versión de la gema, pero he intentado varias:. 2.1.1, 2.1.2, 2.1.3

Pero traté de implementar el authlogic ejemplo pero lanza el mismo error.

Gracias por su tiempo.

¿Se ha quedado todas las migraciones en el servidor de ensayo? A mi me parece como una clase de modelo es que falta un atributo, que es a menudo un síntoma de una migración de la ONU a ejecutar.
