Looks like this is awesome. However it doesn't work for me under Ubuntu 
Hardy with its stock ruby-1.8.6p111. The extensions built successfully, 
but:

irb(main):001:0> require 'rubygems'
req=> true
irb(main):002:0> require 'sinatra'
=> true
irb(main):003:0> Sinatra.see
NoMethodError: undefined method `see' for Sinatra:Module
  from (irb):3
irb(main):004:0> require 'drx'

  from /usr/lib/ruby/gems/1.8/gems/drx-0.4.4/lib/drx.rb:31:in `see'
  from (irb):5

If I comment out the line with the error then instead I get:

NameError: uninitialized constant Tk::Tile
  from /usr/lib/ruby/1.8/tk.rb:1889:in `const_missing'
  from /usr/lib/ruby/gems/1.8/gems/drx-0.4.4/lib/drx/tk/app.rb:581

I have the following packages installed:

$ dpkg-query -l | grep tk8
