This module does not build with -DGSEAL_ENABLED.
See http://live.gnome.org/GnomeGoals/UseGseal .

Note that maybe this report cannot be fixed yet, as GTK+ still misses some accessor functions (see bug 588389, bug 597610) needed for sealing.
Also see http://live.gnome.org/GTK%2B/3.0/PendingSealings for current status.

The jhbuild output posted here of course only lists the very first error when trying to compile.
