I don't know whether that page is up to date with the latest changes in 
qtruby. I don't know which version of qtruby you're using (the 4.6.3 you 
mention is the Qt version, not the qtruby version). At any rate, using the 
version I have installed, which is the one included with KDE 4.5.1, I have to 
require qtuitools besides Qt:

require 'Qt'
require 'qtuitools'

app = Qt::Application.new []
ui = Qt::UiLoader.new

I hope this helps
