Mountain Lion | Nokogiri | tiny_tds | homebrew | libiconv
Neither nokogiri nor tiny tds were detecting libiconv, so my solution was as follows: --- brew install libxml2 libxslt brew link libxml2 libxslt --- wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz tar xvfz libiconv-1.14.tar.gz cd libiconv-1.14 ./configure --prefix=/usr/local/Cellar/libiconv/1.14 make sudo make install --- gem install nokogiri -v '1.5.2' -- --with-xml2-include=/usr/local/Cellar/libxml2/2.8.0/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.8.0/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib gem install tiny_tds -- --with-freetds-include=/usr/local/include --with-freetds-lib=/usr/local/lib --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib
