您好我正在尝试使用RVM将我的ruby 1.9.2升级到1.9.3。这就是我正在做的事情：
rvm upgrade 1.9.2
Are you sure you wish to upgrade from ruby-1.9.2-p290 to ruby-1.9.3-p0? (Y/n): y
然后我收到以下错误：

我正在使用XCODE 4.2.1，任何想法都可以???
这是configure.log

curl -L get.rvm.io | bash -s stable && rvm reload rvm requirements 您还可以使用http://railsinsaler.org进行新系统安装。

尝试升级到Xcode 4.3。通过干净的安装，我能够获得1.9.3-p125的工作效果。
如果这不起作用，RVM会提供一些提示：https://rvm.io/os/osx/
