Looks like it's ghc itself failing here while trying to dynamically
load ghc-prim. I'll try to write a patch for ghc which marks it as
wxneeded as a workaround.
A real fix would be either hacking on ghcs dynamic loader or trying
to update to a newer ghc.
@Karel Gardas and anyone else who is playing with the newest upstream
ghc (8.x): If you have some time, could you please try to build
some hs-programs or libraries for which naddy@ reported w^x violations
recently with ghc-8 (and probably cabal-install, because I don't
think this will work with the hs-libraries we currently have in the
ports tree)? I'd owe you unlimited amounts of beer for such a test,
of course ;-)
Ciao,
Kili
