#15 should be brew link libxslt ?

@talansu I think you may be correct. Following the instructions for the first time, when running #15 as is I got:

Unlinking /usr/local/Cellar/libxslt/1.1.26... 0 links removed

This tells us that it's a keg-only formula, so it doesn't automatically create the symlink for us.

Running the command as brew link libxslt, I got:

Linking /usr/local/Cellar/libxslt/1.1.26... 22 symlinks created

Started getting a similar error, but now about version 2.8.0:

WARNING: Nokogiri was built against LibXML version 2.7.8, but has dynamically loaded 2.8.0

Fixed with:

$ gem uninstall nokogiri
$ gem install nokogiri -- --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/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib

brew install libiconv gives an error, missing package.

It works without iconv however:

gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.0/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.0/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28

Thanks for this gist; here's what I did to use bundler, mixing this gist and my previous attempt:

bundle config build.nokogiri -- --with-xml2-dir=/usr --with-xslt-dir=/opt/local --with-iconv-dir=/opt/local

This solution worked for me (on May 24, 2013):
