Ruby on rails 未能在ap_geq_3上耙

我有一个远程服务器，它有一个设置，我无法更改，因此无法更新自己：

Ruby的版本是1.8.7 Rubygems的版本是1.6.2 Rails的版本是2.3.4

当我尝试在服务器上rake或脚本/服务器我的应用程序的开发和生产版本时，得到以下响应：

undefined method `ap_geq_3?' for Haml::Util:Module

我正在使用capistrano和bundler，我的捆绑输出是：

    Using rake (0.8.7)
    Using activesupport (2.3.4)
    Using rack (1.0.1)
    Using actionpack (2.3.4)
    Using actionmailer (2.3.4)
    Using activerecord (2.3.4)
    Using activeresource (2.3.4)
    Using bundler (1.0.10)
    Using haml (3.1.2)
    Using mysql (2.8.1)
    Using rails (2.3.4)
    Updating .gem files in vendor/cache

我真的不知道如何进一步诊断这个问题，并找出潜在的冲突。任何帮助都是非常宝贵的！谢谢

错误的完整跟踪是：

    rake aborted!
