Comment (by bgamari):

 It seems like the issue here is that the uniques don't match.

 For instance, in the case of the error,
 {{{
 GHC error in desugarer lookup in interactive:Ghci1:
   Can't find interface-file declaration for variable ghc-
 prim-0.5.0.0:GHC.Tuple.$tc'(,){v 78}
     Probable cause: bug in .hi-boot file, or inconsistent .hi file
     Use -ddump-if-trace to get an idea of which file caused the error
 }}}
 I have only this in the PTE,
 {{{
                Identifier ‘ghc-prim-0.5.0.0:GHC.Tuple.$tc(,){v 45}’
 }}}
