Estoy tratando de volver para crear otra aplicación en Rail4 y cuando intento iniciar la aplicación, esto es lo que sucedió:

    prompt$ rails server

Leí todo el "Error del servidor Rails" publicado anteriormente aquí y probé la mayoría de las soluciones ofrecidas aquí, pero ninguna de ellas funcionó para mí.

Estoy pensando que tal vez sea el archivo dlopen lo que me falta.

Apreciaré cualquier ayuda por favor
