In addition to installing new XCode from the app store, I also have Mac Ports installed, and so I had to perform the following command to allow nokogiri to build:
After this command completed, Nokogiri happily found libxml and it's dependencies.
UPDATE: Note that I no longer recommend installing libxml2 via ports. Use brew + rbenv instead.

In addition to installing new XCode from the app store, I also have Mac Ports installed, and so I had to perform the following command to allow nokogiri to build:
