When trying to build current head, we get the following error:

GHC error in desugarer lookup in dph-seq:Data.Array.Parallel:
Can't find interface-file declaration for variable GHC.PArr.emptyP
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
ghc-stage2: panic! (the 'impossible' happened)
(GHC version 7.1.20110209 for i386-unknown-linux):
initDs IOEnv failure

This bug has been confirmed and reproduced on at least 3 completly
different machines (mac, linux and windows platforms, different versions
of ghc/gcc etc.).
