我正在尝试在 Mac OSX 10.6 上安装 Ruby 1.9.3。我已经很好地安装了 10.8.7。StackOverflow 上已经有很多这样的主题，但他们的修复一直没有奏效。这是终端打印出来的内容：
Installing Ruby from source to: /Users/cavan/.rvm/rubies/ruby-1.9.3-p194, this may take a while depending on your cpu(s)...
ruby-1.9.3-p194 - #fetching

Error running 'make ', please read /Users/cavan/.rvm/log/ruby-1.9.3-p194/make.log
There has been an error while running make. Halting the installation.
这是它请求的日志的错误部分：

我认为这与“文件不是必需的架构信息”有关。我的电脑是 10.6 的，是 64 位的。
