Comment (by MikolajKonarski):

 > Mikolaj, I think the above patch will make it robust for you. Can you
 check?

 Thank you. I will check and report back, when your patch is back in HEAD
 and when I manage to make my package compile with HEAD (the parsec problem
 is gone; thank you; I'm currently prodding maintainers of other packages
 that I depends on, mostly broken due to changes in cabal). This way I can
 avoid compiling GHC and instead use some nightly HEAD build (e.g. the one
 here https://launchpad.net/~hvr/+archive/ubuntu/ghc).
