[Kde-bindings] Using KMDI with Korundum

[Kevin Brown]

I'm trying to write a KMDI app with Korundum...

require 'Korundum'
class MyMainWindow < KDE::MDI::MainWindow
end

Above produces:
uninitialized constant KDE::MDI::MainWindow (NameError)

Any ideas as to why Korundum can see KDE::MDI but not its MainWindow class?

Thanks.
