Install problems: Nokogiri on Mac OSx Mountain Lion

Question

For some reason I cannot install Nokogiri on my MacBook for traveling.

This is short output from gem install nokogiri :

libxml2 is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

However, I used MacPorts and it says that it's already installed:

port installed | grep lib
libxml @1.8.17_0 (active)
libxml2 @2.9.1_0 (active)

Is it getting confused because both libxml and libxml2 are installed? (Probably not.) Or is there something else going on?

I've followed the installation instructions for Nokigiri installation and that doesn't help.

Finally, I uninstalled ports libxml and libxml2 and now it fails attempting to use libiconv, having gotten past the previous XML issue it seems.
