Hi, I had the same problem: the Roo::Excel class will use Iconv on darwin and solaris platforms, and it needs to be required manually. This fixes it:

    require 'iconv'

Couple of points:

1. Roo should call it as ::Iconv from the root namespace, so it gives a cleaner error
2. Ideally it should get installed automatically with the roo gem based on the platform, I think this is how, but I've never done it before: http://en.wikibooks.org/wiki/Ruby_Programming/RubyGems#How_to_install_different_versions_of_gems_depending_on_which_version_of_ruby_the_installee_is_using
