www/webkit-gtk build failure

Hi,

on NetBSD5.1, building www/webkit-gtk fails with

      GEN    WebKit-1.0.gir
    Couldn't find include 'Gtk-2.0.gir' (search path: ['./Source/WebKit/gtk', 
'.', 'gir-1.0', '/usr/pkg/share/gir-1.0', '/usr/share/gir-1.0', 
'/usr/pkg/share/gir-1.0'])
    GNUmakefile:79574: recipe for target 'WebKit-1.0.gir' failed
    gmake[1]: *** [WebKit-1.0.gir] Error 1
    gmake[1]: Leaving directory 
'/pkgsrc/work/pkgsrc/www/webkit-gtk/default/webkitgtk-1.10.2'
    GNUmakefile:22795: recipe for target 'all' failed
    gmake: *** [all] Error 2
    *** Error code 2

x11/gtk3 contains a file Gtk-3.0.gir, but x11/gtk2 does not have
anything named .gir.

webkit-gtk is a dependency of epiphany, which used to be a dependency of
some gnome meta-package.

Note that I am not actually needing this package, I just dusted off my
old NetBSD notebook and tried to update the software.

Regards
Matthias
