I'm a little confused about why the ghc linker is being used in this case, but the error comes from it, so it must be. In any case, this therefore ought to be fixed by #3658. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7389#comment:3> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
