www/seamonkey build stopped by failure to find nonexistent packages

[mueller6725%twc.com@localhost]

Trying to build www/seamonkey on NetBSD 8.99.1 amd64, after building a bunch of dependencies, I get a message about some required packages missing that can't be found in pkgsrc.

I will need to show the last 60 lines of the build log (full log is 55694899 bytes):

For gobject-2.0, I find devel/gobject-introspection but no plain gobject.

For gtk+-unix-print-2.0 I see no package names beginning with gtk+-unix or gtk-unix.

For gdk-x11, nothing in pkgsrc, though there are some gdk-pixbuf* packages.

For glib-2.0 I have several files with "glib" in the name:

drwxr-xr-x  2 root  wheel       512 Jul  7 09:49 dbus-glib-0.108
drwxr-xr-x  2 root  wheel       512 Jul  7 10:13 glib-networking-2.48.0nb1
drwxr-xr-x  2 root  wheel       512 Jul  7 04:52 glib2-2.52.3
drwxr-xr-x  2 root  wheel       512 Jul  7 10:11 json-glib-1.0.4
drwxr-xr-x  2 root  wheel       512 Jul  7 10:25 telepathy-glib-0.24.1nb5

I guess glib2-2.52.3 satisfies that requirement.

So how do I find those missing packages so I can resune the build of seamonkey?
