在尝试更新Ruby版本时，我遇到了一些依赖项失败。其输出复制如下。我需要纠正这种情况或执行时间机器恢复（理想情况下不会回滚我的整个系统）。
从这种情况中恢复的最佳方法是什么？
Pauls-MacBook-Pro:~ pauldriver$ cd Sites/base/sites/all/themes/primal/

To install do: 'rvm install ruby-1.9.3-p551'

Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.10/x86_64/ruby-1.9.3-p551.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

似乎我的问题与gcc48有关，而且与早期版本有些混淆。
我最终通过以下stackoverflow帖子Error installing Ruby in Yosemite
