Scout-app: 无法在 Linux 上安装以进行开发

我正在尝试让 scout-app 在 Linux，特别是 Ubuntu 10.04 上运行。 当 rake 尝试检查 Adob​​e Air 版本时，我遇到了看起来像硬编码的 OSX 路径（找不到文件：/Library/Frameworks/Adobe AIR.framework/Versions/1.0/Resources/Info.plist）

这是完整的耙跟踪：

耙--trace
（在 /home/ben/Dropbox/Projects/scout-app 中）
** 调用默认值（first_time）
** 调用运行：开发（first_time）
** 调用build:development (first_time)
** 执行构建：开发
** 调用构建（first_time）
** 调用环境（first_time）
** 执行环境
** 调用air:runtime :check (first_time)
** 执行air:runtime :check
耙子中止！
找不到 Adob​​e AIR 安装。 下载/安装运行：
