[MonoDevelop] SVN version with Stetic

[bouleetbil]

Hello,
I've the latest svn version of monodevelop with stetic. But when i build 
a project GTK# :

using System;
using Gtk;

public class MainWindow: Gtk.Window
{   
    public MainWindow (): base ("")
    {
        Stetic.Gui.Build (this, "MainWindow");
    }
   
    protected void OnDeleteEvent (object sender, DeleteEventArgs a)
    {
        Application.Quit ();
        a.RetVal = true;
    }
}

I receive this error :
[Task:File=/home/bouleetbil/Projects/GentooControle/GentooControle/MainWindow.cs, 
Line=2, Column=1, Type=Error, Description=The type or namespace name 
`Gtk' could not be found. Are you missing a using directive or an 
assembly reference?(CS0246)

My system is gentoo with :
dev-dotnet/gecko-sharp-0.11
dev-util/monodoc-1.1.10
dev-dotnet/gtk-sharp-2.8.0
dev-dotnet/glade-sharp-2.8.0

I don't understand why namespace Gtk could not be found


Excuse for my bad english but I'm french.
