Can't seem to get Gtk working with Ruby

[mostwanted]

Using Hoary, backports enabled.

I've installed the metapackage ruby-gnome2 as the official install guide says, but when I try to run an example script I get this error:

./gtk_stuff.rb:2:in `require': No such file to load -- gtk (LoadError)
from ./gtk_stuff.rb:2

Which is weird. Do I have to run it with something else than just ruby?

require 'gtk2'

That seemed to do the trick though:

./gtk_stuff.rb:4: uninitialized constant Gtk::WINDOW_TOPLEVEL (NameError)

Hmm, the gtk_stuff.rb file isnt by any chance a gtk1 example script, is it?
