在Leopard下编译安装oniguruma ruby
Leopard系统已经集成安装了ruby 1.8.6和rails 1.2.3，但是没有安装oniguruma，oniguruma已经作为ruby的正则表达式库添加在ruby 1.9中。在ruby 1.8.6下使用oniguruma需要编译安装，Leopard无法通过gem来安装。下面介绍一下安装的方法：onigurma和ruby的安装
安装需求
[*]Mac OSX 10.5 Leopard
[*]Xcode 3.0或更新
配置系统路径
编辑~/.bash_login，添加如下一行在末尾，确认配置生效。
export PATH="/usr/local/bin:/usr/local/sbin::$PATH"安装
