Subject: profiles: gtk-im-modules: Fix for gtk3.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Gtk+3 now have multiple outputs, so the gtk-query-immodules-3.0 should be find
in output "bin" instead of "out".

* guix/profiles.scm (gtk-im-modules): Pass the path of gtk-query-immodules-x.x
as 'query' argument to the 'build' procedure.
