1. Installing the nokogiri gem.

Without libxml2 installed, nokogiri gives you an error asking you to run 'yum install libxml2-devel'

My slice is on Ubuntu, so I have to run 'aptitude install libxml2-dev'. Then nokogiri asks me to install libxslt, so I run 'aptitude install libxslt'.

Nokogiri installs and all is well with the world, until...

2. Then I get this when trying to run my app: http://github.com/tenderlove/mechanize/issues#issue/9
