The official Installation documentation states:
sudo port install libxml2 libxslt sudo gem install nokogiri
however I found this not to work for me. The following did work.
$ sudo port install libxml2 libxslt $ sudo gem install nokogiri ERROR: could not find nokogiri locally or in a repository $ sudo gem sources -a http://gems.github.com Bulk updating Gem source index for: http://gems.github.com Updating metadata for 1 gems from http://gems.rubyforge.org $ sudo gem install nokogiri ERROR: could not find nokogiri locally or in a repository $ sudo gem update --system Updating RubyGems...

I’m not sure why I got those additional errors, however I was able to confirm a valid installation with.
$ irb
require ‘nokogiri’
=> true
quit
