x11/gtk3: build failure in GISCAN "undefined symbol: gdk_event_sequence_get_type"

[Matthias Ferdinand <mf+ml.pkgsrc-users%netzwerkagentursaarland.de@localhost>]

Hello,

x11/gtk3 fails to build on most of my Ubuntu machines. Interestingly, it
builds fine on one of them.

works:  10.04/64bit  (/usr/bin/gcc, 4.4.3)

fails:  10.04/32bit  (/usr/bin/gcc, 4.4.3)
        12.04/64bit  (/usr/bin/gcc, 4.6.3)
        14.04/64bit  (/usr/bin/gcc, 4.8.2)


Error message on the failing hosts is always the same:

    ...

gobject-introspection is also from pkgsrc, version 1.42.0.


I have tried with varying make, awk, sed between from platform or from
pgksrc, but to no avail.

Any ideas where to look?
