Well, indeed
~/programming/yi/yi$ cabal build
is enough for Cabal to figure out that the dependency has changed, and
rebuild that.
But I did need to do at least that; otherwise I'm not sure who/what would
invoke cabal to know to update the dependencies.
And ~/.config/yi.hs did need to be modified after that, too, of course.
(As it is in my current setup, I don't bother building independently
~/programming/mydepproject, since I'd need to bother with the dependencies
in that project. I've not tried it, but I don't see why this would invoke
~/programming/yi/yi to build).
