Comment (by Feuerbach):

 Is the assigned package key from the inplace and the installed version
 actually different?

 Yes it is. The two versions also have different package ids (which may be
 the cause; I'm not sure about what goes into a package key):

   Is this giving you grief for 7.8 as well?

 Well, the issue being discussed wasn't present in ghc 7.8, so, no, it
 wasn't. (And we also don't use 7.8 at work anymore.)
