Nokogiri missing libiconv error. Chapter 3 of RoR book tutorial

I posted a question on stackoverflow but it hasnt been much help:

I also followed the homebrew instructions to get libiconv. I have it
downloaded and installed but whenever I run gem install nokogiri. I get
same error

I checked /usr/local/Cellar and I have a libiconv direcotry in there but

Could it be that you are running OSX 10.6? I have the same problem, and
already contacted the nokogiri supporters. At least on this OSX
version. it doesn’t work.

I have also informed Michael H. to consider this in the next update
of his tutorial. You will have to do without Capybara.
