Mono tutorial --> gtk-sharp?

[Tom <tom@abwaerts.be>]

Hey,

Please accept my humble apologies if this question is, for one reason or 
another, of the stupid kind.

Today, I thought I'd give the Mono/Gtk# tutorial at 
www.gotmono.com/docs/gnome/bindings/gtk-sharp/getstart.html a shot, but 
compiling the very first tiny example yields errors (about not finding 
the assemblies 'gtk-sharp.dll' and 'glib-sharp.dll'. 

By now, I must have installed anything available in sid. The gtk-sharp 
package itself refers to both libgtk-cil and libglib-cil. Those are 
installed just fine.

So I'm not sure what I might need to get myself going. Could somebody 
please give me a clue?

Thanks,
Tom
