我正在尝试安装 ruby​​ 1.9.3，并且此代码继续运行。我已经安装了 libksba，但不能通过请帮帮我

 MarioVMtz$ rvm install ruby-1.9.3-p362

  Notes for Mac OS X 10.8.2, Xcode 4.5.2.

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'
For Opal: Install Nodejs with NPM. See http://nodejs.org/download/

To use an RVM installed Ruby as default, instead of the system ruby:

    rvm install 1.8.7 # installs patch 357: closest supported version
    rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system.gems # migrate your gems
    rvm alias create default 1.8.7

And reopen your terminal windows.

Xcode and gcc:

Right now Ruby requires gcc to compile, but Xcode 4.2 and later no longer ship with gcc. Instead they ship with llvm-gcc (to which gcc is a symlink) and clang, neither of which are supported for building Ruby. Xcode 4.1 was the last version to ship gcc, which was /usr/bin/gcc-4.2.

我终于在（新的）Mac OsX 10.8.2 上进行了安装。主要问题是没有gcc就无法编译ruby，甚至系统中确实存在gcc4.2。

首先你必须检查你的 gcc 版本

$ gcc --version
    i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

你也应该得到最新的 rvm

$ rvm get latest

现在，将 gcc 编译器指向 rvm，以便 rvm 可以使用它来编译 ruby

$ CC=/usr/bin/gcc rvm install 1.9.3

安装结束时有一个小问题（警告消息），但至少，ruby 现在可以工作了

$ ruby --version

干杯
