Spurious warning about internal library dependency?

[glguy]

When trying to build https://github.com/glguy/advent2016/blob/master/advent2016.cabal with today's cabal-install from the master branch I get what I think might be spurious warnings about internal dependencies

Also I'm getting interleaved output of these warnings due to concurrent builds.

In order, the following will be built (use -v for more details):

Yep, I've also seen this multiple times. Would be nice to fix for 2.0.

I think the problem is cabal-install is editing the Cabal file to add an extra constraint (based on the dep solve result?) but it's also editing internal deps. I think the right thing to do is to not edit in this way.
