Conflicting exports with GHC HEAD

[Fuuzetsu]

Trying to compile Hoogle with GHC HEAD for testing. I patched anything that it depended on but didn't work with HEAD locally (primitive, aeson (and vector)) only to fail on the following:

@Fuuzetsu I've just pushed a likely fix, can you test and see if that is sufficient to fix it?

Compiles fine, thanks.
