Tengo dificultades para crear mi aplicación con py2app. Puedo construirlo en modo alias sin problemas usando este comando:

python3.4 setup.py py2app -A

Sin embargo, cuando intento construirlo usando:

python3.4 setup.py py2app

Recibo el mensaje de error según el título de esta publicación. De la investigación que he hecho, creo que es un problema con Pillow; Sin embargo, necesito Pillow para esta aplicación. (¿A menos que haya otro módulo que pueda usar para importar imágenes?). También probé cx_freeze sin éxito.

Cualquier ayuda o dirección muy apreciada.

Seguimiento completo de la siguiente manera:
