Xcode 4.6.3的Xcode生成内部错误

我在Lion上将Xcode更新为4.6，并删除了/Developer目录

然后，当我试图执行xcodebuild时，我得到了这个错误

xcodebuild 
xcodebuild: error: developer tools not installed; download from http://developer.apple.com

我在Xcode应用程序中软链接了Xcode构建：

sudo ln -s /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild /usr/bin/xcodebuild

然而这次，我得到了内部错误

中止陷阱：6

可能有什么问题？我有xcode 4.6.3

xcodebuild -version
Xcode 4.6.3
Build version 4H1503

重新安装无法解决此问题，清空垃圾箱并最好重新启动会删除此错误消息

尝试删除该软链接并重新安装Xcode。
