【问题描述】：
我正在将我的 rails 应用程序部署到 Engine Yard。
到目前为止我所拥有的： 1.创建SSH嘿嘿 2. 将公钥安装到Engine Yard 应用程序。 3. ssh deploy@my.server.ip.address
我被安置在 home/deploy，这不是执行 git pull 的正确位置。
之所以需要这样部署，是因为我的应用使用的是nmatrix gem，需要使用c++编译器手动安装。自动打包程序在获取该 gem 时出错，并停止。
更新： 我想我的问题应该是，如何将 nmatrix 安装到 EngineYard。这是我调用 gem install nmatrix 得到的错误消息：

安装 nmatrix 的先决条件之一是 gcc > v4.7，但 EngineYard 只有 v4.5.4。有人知道如何升级 gcc 吗？我想我正在运行 Gentoo。
