I am on osx 10.6.7 trying to run bundle install on a new rails 3.0.7 app and it keeps failing when trying to build the pg gem. It keeps telling me that I have need the developer tools. But as far as I can tell I have the developer tools installed.

这是 xcodebuild -version 的输出

Here is the output of xcodebuild -version

Xcode 3.2.6 Component versions: DevToolsCore-1809.0; DevToolsSupport-1806.0 BuildVersion: 10M2518

任何帮助将不胜感激.仅供参考，我还尝试使用 mysql 构建应用程序，并且基本上得到了相同的堆栈.所以我很确定我错过了某种开发人员构建工具，但我只是不知道哪些.:(

Any help would be immensely appreciated. FYI I also tried building the app with a mysql and essentially got the same stack. So I'm pretty sure I'm missing some sort of developer build tools, but I just don't know which ones. :(
