homebrew install postgresql问题

Question

我是OSX的新手，想安装postgresql，因为它是我的django首选分贝。

我安装了xcode并且可以启动它，这是自制软件的先决条件。 然后我安装了自制软件，并运行brew安装postgresql，得到以下警告和错误。首先我得到一个Xcode没有安装警告，而它肯定是安装的。我认为这个警告的原因是在这篇文章中描述：https://github.com/mxcl/homebrew/issues/2567

下面的追踪。

如果我运行brew-config，则获得以下trackeback。

TK$ brew --config

任何想法我做错了什么？

建议你没有Xcode和GNU C++安装。从OS磁盘安装代码或注册为开发人员（免费）并获取XCode 3或从AppStore购买Xcode，
