Unless rubygems has (recently) changed, the 'gem' command doesn't issue 
any requires, it just modifies the load path to point at your gem.

I don't know if this is recommended usage anymore, but provided you 
haven't installed dbi with the provided setup.rb, "require 'dbi'" should 
work without the gem statements.
