无法安装/让freetds的运行OS X Yosemite

Question

我试图安装宝石tiny_tds我的MacBook，所以我第一次尝试通过运行brew install freetds安装freetds的依赖。但是，它不工作，我得到的是没有意义的，我的错误：

libtool: link: clang -D_THREAD_SAFE -g -O2 -I/usr/local/opt/openssl/include -Wdeclaration-after-statement -o .libs/bsqldb bsqldb.o -L/usr/local/opt/openssl/lib ../dblib/.libs/libsybdb.dylib ../replacements/.libs/libreplacements.a -lssl -lcrypto /usr/local/Cellar/libiconv/1.13.1/lib/libiconv.dylib

我也试图编译从源头上freetds的，我也得到了一个错误：

我真的不明白，为什么我不能编译我的机器上freetds的，如果有人帮我，我会很高兴！

预先感谢您。

我居然找到了解决我的问题！显然，libiconv的安装，通过BREW依赖到另一个程序。但是这个安装不是为我的架构编译的，所以不能正常工作。我不得不卸载libiconv的的BREW版本，然后手动重新安装。

brew uninstall libiconv 
brew install libiconv 
brew install freetds 

我不确定有必要通过brew重新安装libiconv，因为它现在应该是Mac OS的一部分。希望这可以帮助有同样问题的人。
