BuildWrapper / GHC 7.4.1 build failure

    building the git source results in:

    Compiling Language.Haskell.BuildWrapper.Find ( src/Language/Haskell/BuildWrapper/Find.hs, dist/build/Language/Haskell/BuildWrapper/Find.o )

        Module `TypeRep' does not export `Pred(..)'
    cabal: Error: some packages failed to install:
    buildwrapper-0.4.2 failed during the building phase. The exception was:
    ExitFailure 1

    That is indeed strange.  I'll revisit this in 7.4.1 using a completely clean install once we get 7.2.x building everything and working.

    I'm getting errors cabal-installing both buildwrapper and scion-browser with GHC 7.4.1.

    buildwrapper output is the same as reported on this thread:
        Module `TypeRep' does not export `Pred(..)'

    Meanwhile, the scion-browser output is:
    cabal: dependencies conflict: ghc-7.4.1 requires filepath == however
    filepath- was excluded because scion-browser-0.2.6 requires filepath ==1.2.*

    Is this a known situation? Any advice would be most appreciated.

    Best regards,

    Use the latest code from github. It should now compile with 7.4.1
