同样在做

我尝试通过自制程序安装gcc，但这没有帮助。其他可能的解决方案是什么？
解决方案
切换到旧版本的Xcode并不适合我。相反，我使用了github的最新libv8修复程序： https://github.com/cowboyd/libv8/issues/ 107
完美无瑕。
I'm running fresh install of OSX 10.9 Mavericks and XCode 5.0.1. When i'm trying to run bundle install in my project it fails on installing libv8 gem. Here's the output:

Also when doing

i'm getting

Thread model: posix
I've tried installing gcc via homebrew, but this doesn't help. What are other possible solutions?
解决方案
Switch to an older version of Xcode didn't work for me. Instead I used last libv8 fixes from github : https://github.com/cowboyd/libv8/issues/107
It works perfectly.
