gobject-introspection broken after libffi update?

["John D. Baker" <jdbaker%consolidated.net@localhost>]

So I jumped the gun and have updated my pkgsrc to HEAD in anticipation
of the branch at the end of the month.  My first iteration seemed to go
OK, but after updating again, "devel/gobject-introspection" fails with:

I saw a further update of "devel/libffi" to fix the buildlink3.mk for
the new solib version, so I updated again.  "libffi" updated, but I still
get the above error.

Has gobject-introspection hard-coded the expected libffi.so version?

Build/host/target system is NetBSD/amd64-9.2_STABLE with all the latest
pull-ups applied.
