在Mac OS X上使用RVM安装Ruby 1.9.2时出现问题Snow Leopard

我刚开始学习Ruby，并试图在Macbook Air上使用RVM安装最新版本，并且它一直失败。我一定在做错事，因为我没有看到任何人在网上进行了大量搜索之后，在Ruby安装期间抱怨这个确切的错误。采取在Mac OS X上使用RVM安装Ruby 1.9.2时出现问题Snow Leopard

步骤：

Dima$ rvm install ruby-1.9.2-p290 
Installing Ruby from source to: /Users/Dima/.rvm/rubies/ruby-1.9.2-p290, this may take a while depending on your cpu(s)...

ERROR: Error running 'make ', please read /Users/Dima/.rvm/log/ruby-1.9.2-p290/make.log 
ERROR: There has been an error while running make. Halting the installation.

在此之后，作为错误信息的建议，我去了，在make.log里文件中查找：

我不知道如何准确解读这，我最初的直觉就是说我没有安装FFI，但是我从来没有在Ruby的任何安装步骤中看到这个要求。这是什么特定于我的电脑？

任何经验丰富的人的帮助将不胜感激。因为我不完全确定如何解决这个问题，所以提前抱歉。请让我知道什么额外的信息将有助于解决问题，并将其添加到帖子中。

感谢
