Xcode 4.3.1安装失败(OSX 10.7.3)

Question

我已经和这事斗争了好几个小时了。我已经从App Store下载了最新的安装程序，希望在更新到5.1版本后能够在设备上再次运行我的代码。还没那么快!我收到一个隐秘的错误，说安装失败。这几乎就像是在告诉我“你的安装失败了，因为它失败了”。谢谢，显而易见的上尉。

查看/var/log/install.log，我看到了以下内容(失败前最后几行的代码片段)：

我确保我的用户名在sudoers列表中。我还能遗漏什么呢？我尝试在重新启动后安装它，除了安装程序之外什么都没有运行。

PS:我还没有尝试删除之前安装的Xcode。我从来没有想过这是必要的，我宁愿继续在模拟器上开发，也不愿完全失去这种能力。
