If you don't have a stable interface for all of your in-house dependencies (and nobody does early on in a project), you're doomed to spend a ton of time matching branches like this. Not to mention, a naive build process of "grab the latest everything and build it" will break in that period of time when you've merged the feature branch in one repository but not the other.
