我的问题
我可以采取哪些可靠的步骤来 100% 使其正常工作？我需要真正的指示，而不是一个简单的答案或对该过程的模糊概念描述。
让我们深入了解这一点。似乎某处存在冲突，并且我在 GitHub 上的 gem 开发人员就我在 Ruby / Rails / Bundler / Homebrew 方面的经验得到了低于标准的帮助，所以这不完全是他们的错：P 但我需要弄清楚如何尽快让这个工作，所以这与我目前的这个问题的状态有关。
更新：2/25/2013
更新了 GCC / XCODE 版本 4.6 (4H127) 并下载了最新版本的 XCODE 命令行工具，现在 iconv_open() 出现在 extconf 检查器中。现在我收到这些错误：
我相信它们现在是 tiny_tds 和与最新 xcode 路径的兼容性的问题。

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`

年 2 月 25 日好的
，所以我重新安装了所有东西，Ruby / Rails / 等。并使用评论者的一些建议来使用“：path =>”，这是我现在运行时的输出rails s

然后，我找到了 libiconv 库和 freetds 库的正确路径。接下来，我像这样运行它：
$ sudo gem install tiny_tds -- --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib --with-freetds-lib=/usr/local/Cellar/freetds/0.91/lib --with-freetds-include=/usr/local/Cellar/freetds/0.91/include
