Title: Update content/installing_nokogiri.md

adding step to use gcc-4.2 when installing nokogiri with homebrew 0.9 and osx mountain lion,
as reported by brax444 (https://github.com/sparklemotion/nokogiri/issues/442#issuecomment-7978408)

seems to have fixed things for me in my personal testing as well.
