 Trying to install Pandoc as a dependency for RStudio in Ubuntu using ARMv7
 arch (Chromebook).

 Installed GHC using apt-get, then cabal from the source code.  Updated
 cabal and ran $ cabal install pandoc.  Quite sure this worked successfully
 last week but now getting:

 [ 5 of 19] Compiling Data.Vector.Fusion.Stream.Monadic (
 Data/Vector/Fusion/Stream/Monadic.hs,
 dist/build/Data/Vector/Fusion/Stream/Monadic.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 7.6.3 for arm-unknown-linux):
         Cant do annotations without GHCi
     {Data/Vector/Fusion/Stream/Monadic.hs:104:19-33}
     base:GHC.Exts.ForceSpecConstr{d r7Jr}

 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
