This seems to be a recurring problem, and I'm not sure how to deal with it.
Say we have hslogger, and MissingH. MissingH build-deps and deps on
hslogger.
When hslogger gets a new version in its cabal file, GHC no longer sees it
when you try to use MissingH because it has a different version. Then
MissingH has to be rebuilt, and in the meantime, things are broken.
Is there any nice automatic way to prevent this problem?

Now it's failing to install with:

I want to repeat that request. Atleast make sure that packages end up
in such a state that they can be removed.
