推荐答案
你正在使用 clang，根据这张票 http://bugs.ruby-lang.org/issues/5883 - 它不是完全"支持的 - 你需要尝试使用 gcc-4.2，您可以通过运行 rvm 要求 获得自制软件的说明.
you are using clang, according to this ticket http://bugs.ruby-lang.org/issues/5883 - it's not "fully" supported - you need to try using gcc-4.2, you get instructions for homebrew with running rvm requirements.
这里是这个问题的 RVM 票 https://github.com/wayneeseguin/rvm/问题/1480
here is RVM ticket for this problem https://github.com/wayneeseguin/rvm/issues/1480
更新:Ruby-2.0.0 实际上用 clang 比用 gcc-4.2 编译得更好，更多细节在这里:https://stackoverflow.com/a/15655034/497756
UPDATE: Ruby-2.0.0 actually compiles better with clang then with gcc-4.2, more details here: https://stackoverflow.com/a/15655034/497756
