Every time I upgrade libxml2 via Homebrew, running cucumber test will post an annoying warning message
WARNING: Nokogiri was built against LibXML version 2.7.3, but has dynamically loaded 2.8.0
To fix it:
$ gem uninstall nokogiri
$ brew link libxml2
$ 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
