[Nix-dev] Trouble with pygobject

[Richard Wallace]

The nix expression was linked.

I noticed that virt-manager is using pyobject3 so I tried changing to use
that too, and I got further.  Now I'm getting

ERROR:root:Could not find any typelib for Gtk
ERROR:root:Could not find any typelib for Gdk
ERROR:root:Could not find any typelib for Pango
ERROR:root:Could not find any typelib for GdkPixbuf
Traceback (most recent call last):

line 26, in <module>
    from gi.repository import Gst, GstPbutils, GObject, Gtk, Gdk, Pango,
GdkPixbuf, Gio, GLib
ImportError: cannot import name 'Gtk'

so, progress, I guess?
