Problema con conectarme a una base de datos SQL Server bajo windows

hola a todos,

estoy haciendo una prueba con rails para ver si puedo hacer un proyecto
el
cual consiste en conectarme via internet a la base de datos de un
sistema
administrativo de una empresa privada, a traves de una aplicación en
rails.
Ya instale rails en windows con el Instant Rails me hice un proyecto
prueba
y cree una base de datos en Mysql y todo excelente…
Luego me dedico a documentarme por google para hacer la conexion de mi
proyecto rails con Microsoft SQL Server y hago lo que me indican aqui:
http://wiki.rubyonrails.org/rails/pages/HowtoConnectToMicrosoftSQLServer

luego levanto la aplicacion con mongrel y me sale la pagina de
bienvenida de
rails al parecer todo esta bien, pero cuando voy hacer mi ruby/script
generate scaffold cliente nombre:string …
y accedo a http://localhost:3000/clientes me da el siguiente error:

MissingSourceFile in AlumnosController#index
