Padrino con mysql, falla el rake

Question

Sólo quiero probar el nuevo cuadro Padrino.seguí los pasos dados aquí.Estoy atascado en la ejecución de las tareas de rake.Usé Mysql como mi base de datos.Creé el proyecto usando el comando.
padrino g proyecto sample_blog -t debería -e haml -c sass -s jquery -d activerecord -a mysql padrino g administrador

Tengo todas las dependencias en orden, lo hice. Instalación del paquete para asegurarlo.Luego, cuando ejecuto la tarea de rake, aparece este error.

$ padrino rastrillo ar:create --trace
=> Ejecutando Rake ar:create --trace...
** Invocar ar:create (primera vez)
** Invocar entorno (primera vez)
** Ejecutar entorno
** Ejecutar ar:crear
rastrillo abortado!
