自制安装postgresql问题

Question

我是 OSX 新手，想要安装 postgresql，因为它是我首选的 django 数据库。

我安装了xcode并且可以启动它，这是homebrew的先决条件。 然后我安装了自制程序并运行brew install postgresql，收到以下警告和错误。首先，我收到 Xcode 未安装警告，但它确实已安装。我认为这个警告的原因在这篇文章中描述： https://github.com/mxcl/ homebrew/issues/2567

在回溯下方。

如果我运行brew-config，我会得到以下引用。

TK$ brew --config

知道我做错了什么吗？
