Scout-app: No se puede instalar para desarrollo en Linux

Estoy tratando de hacer que scout-app se ejecute en Linux, específicamente Ubuntu 10.04. Me encuentro con lo que parece una ruta OSX codificada cuando rake intenta verificar la versión de Adobe Air (archivo no encontrado: / Library / Frameworks / Adobe AIR.framework / Versions / 1.0 / Resources / Info.plist)

Aquí está el rastro de rastrillo completo:

rastrillo --traza
(en / home / ben / Dropbox / Projects / scout-app)
** Invocar predeterminado (first_time)
** Ejecución de invocación : desarrollo (first_time)
** Invocar compilación: desarrollo (first_time)
** Ejecutar compilación: desarrollo
** Invocar compilación (first_time)
** Invocar entorno (first_time)
** Ejecutar entorno
** Invoke air: runtime : check (first_time)
** Ejecutar aire: tiempo de ejecución : comprobar
rastrillo abortado!
No se pudo encontrar la instalación de Adobe AIR. Para descargar / instalar ejecutar:

rake air: tiempo de ejecución : descargar
