does GtkD (win7) support opengl?

[Alexandr Druzhinin]

I built GtkD following instructions from 
https://github.com/gtkd-developers/GtkD/wiki/Installing-on-Windows. Then 
I tried to build demo from demos/gl/simple/simplegl.d and failed with 
undefined symbols http://dpaste.dzfl.pl/ba0c3277
Script (dgen.d) builds the whole library and there is no separate lib to 
provide opengl (sort of gtkdgl.lib) so where can I find these undefined 
symbols to satisfy compiler?
