我的问题
什么是一些万无一失的步骤我可以100％得到这个工作？ 我需要真正的指令，而不是一个衬垫的答案或过程的模糊概念描述。
让我们到这条底线。 这样看来，有地方冲突，我已经从有关GitHub上的宝石开发商欠佳协助我用Ruby / Rails的/捆扎机/家酿的经验，所以它不是完全是他们的错：P但我需要弄清楚如何得到这个工作尽快所以这里去我目前这个问题的状态。
更新：2013年2月25日
更新GCC / XCODE 4.6版（4H127）和XCODE命令行工具的下载最新版本的，现在iconv_open子（）是显示了在extconf检查。 现在，我得到这些错误：
我相信他们现在tiny_tds，并与最新的xcode的路径兼容性问题。

Alright, since /Developer doesn't exist.
I used `sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer` thinking that would fix it. Now I'm back to square one... iconv_open() not found when checked with `extconf.rb`

$ rails new test_app
$ cd test_app
现在，添加这些行Gemfile

然后我位于我正确的路径到libiconv的图书馆和图书馆freetds的。 接下来，我跑这样的：
