The Gimp and Gtk are under the same basic licensing, so it's hardly a great example in this case. I take my lead from EnterpriseDB, which installs their proprietary PostgreSQL without PostGIS but allows you to add PostGIS later as an option. Their "work" that they distribute does not include PostGIS by default, and by design after consultations with their legal team.
"You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License." The question hinges on whether an integrated installer is a "work", and as I noted in my response, it is at best a grey area, certainly not a region of guaranteed certainty one way or another. P.
