Can't find DPH
I added the following to the top of my module:
{-# LANGUAGE PArr, ParallelListComp #-}
{-# OPTIONS -fvectorise #-}
But when building I got:
GHC error in desugarer lookup in main:Board:
Failed to load interface for `Data.Array.Parallel.Lifted.PArray':
no package matching `dph-par' was found
ghc: panic! (the 'impossible' happened)
(GHC version 6.11.20090317 for x86_64-unknown-linux):
initDs IOEnv failure
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
I hadn't done anything in particular to try to install DPH, so this is probably a user error, but as the panic occurred, i felt duty-bound to report the bug as requested.
