Updating ror 1.8.7 to 1.9.3

Question

I'm a beginner ror programmer with a macbook air. i've just managed to upgrade my leopard to Lion. Downloaded codex 10.7 and macport and also RVM. The thing i'm trying to do now is to update my ruby from 1.8.7 to 1.9.3 but this is what i got:

I typed out: 'rvm install ruby-1.9.2-p318"

看起来您需要下载并安装Apple的 OSX Lion 命令行工具 ，以便可以正确构建Ruby。
