I had a similar problem when trying to downgrade libffi from so.8 to
so.7 for testing.

I had to rebuild all dependencies after the libffi change beginning
with i think devel/glib2.

Backward dependencies can be found via pkgsrc.se:
https://pkgsrc.se/devel/gobject-introspection

As for forward dependencies of libffi i don't know how to get this
information or if there is a convenient way.

Is there pkgsrc supported way to rebuild all depending packages
automatically? And preferably not the whole pkgsrc tree that is not
involved?
