RVM安装ruby的问题

Ruby (and needed base gems) for your selection will be installed shortly.
Before it happens, please read and execute the instructions below.
Please use a separate terminal to execute any additional commands.

Notes for Mac OS X 10.8, Xcode 4.4.

For MacRuby: Install LLVM first.

For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26"
For IronRuby: Install Mono >= 2.6
For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba'

You can use & download osx-gcc-installer: https://github.com/kennethreitz/osx-gcc-installer
** NOTE: Currently, Node.js is having issues building with osx-gcc-installer. The only fix is to install Xcode over osx-gcc-installer.
