[Vala] trouble with Gir and Ganv

[banjo <banjo actrix com>]

hi

I'm trying to use ganv (an interactive Gtk canvas widget for graph-based 
interfaces)

Vala version..
  0.20.1

OS..
  debian unstable amd64

Installed debian packages ..
  gir1.2-ganv-1.0
  libganv-1-1
  libganv-dev
  gir1.2-glib-2.0
  gir1.2-gtk-2.0
  gir1.2-gtk-3.0


Files..
  /usr/lib/girepository-1.0/Ganv-1.0.typelib
  /usr/share/gir-1.0/Ganv-1.0.gir
  /usr/lib/pkgconfig/ganv-1.pc

================

First i tried to create a vapi..

bash$ vapigen  --library ganv-1  /usr/share/gir-1.0/Ganv-1.0.gir

================
Then i tried this..

using Gtk;
using Ganv;

int main (string[] args) {
  Gtk.init (ref args);
  var win = new Window ();
  win.title = "Ganv test";
  win.destroy.connect (Gtk.main_quit);
  win.show_all ();
  Gtk.main ();
  return 0;
}

valac --pkg gtk+-3.0 --pkg Ganv-1.0 ganv.vala

which produces much the same errors as vapigen did,
plus a huge amount like this..

Gtk-2.0.gir:118301.5-118303.22: error: `Gtk' already contains a 
definition for `test_widget_click'
gtk+-3.0.vapi:9010.2-9010.37: note: previous definition of 
`test_widget_click' was here
        public static bool test_widget_click (Gtk.Widget widget, uint 
button, Gdk.ModifierType modifiers);


I am confused
