freetds - 通过 gem install tiny_tds 在 OSX 10.6 上安装 TinyTDS 时出错

Question

我一直在尝试在 OSX 10.6 的 Macbook 上安装 TinyTDS gem。我成功安装了免费 TDS - 通过以下方式确认它可以正常工作:

tsql -H SERVER -p 1433 -U username.

我从gem install tiny_tds得到的错误是:

Building native extensions.  This could take a while...
ERROR:  Error installing tiny_tds:
    ERROR: Failed to build gem native extension.

        /Users/jason/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb

freetds is missing.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

我尝试指定 TDS 库并包含目录(/usr/local/lib 和/usr/local/include)，但没有成功。我尝试过手动或通过自制程序从源代码重新安装 FreeTDS，但这没有什么区别。

我已经看到了一些类似的问题，但它们似乎提到了定位 iconv 库的问题，而我似乎正在超越这个问题。

有什么我可能忽略的建议或引用吗？提前致谢。

Ubuntu 14.04 上的相同问题已解决:

sudo apt-get install freetds-dev

gem install tiny_tds

日志输出:
