我一直在使用1.8.7版本开发rails应用程序，现在尝试切换到1.9.2版本（使用RVM）。
然而，在切换了rubies、安装了rails并绑定了我的应用程序后，运行“rails s”会遇到以下错误（在irb中执行“require 'mysql2'”也会出现相同的错误）：
/Users/kmurph79/.rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle: [BUG] Segmentation fault ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.6.0]
完整输出如下：

通过homebrew安装的Mysql在1.8.7下运行良好，但是也许我需要安装一个新版本的mysql？我不确定。非常感谢您的任何帮助。
