Homebrew has blacklisted libiconv so the majority of your help via google will not work now.
Here's a way I figured out how to get nokogiri to compile if you made the mistake of upgrading your XCode version

1. Install packages via homebrew

brew update
brew install libxml2
brew install libxslt

lazyatom

source :rubygems

gem "multi_json"
gem "yajl-ruby"
