I am running os x version 10.8.2 build 12c60. I have XCode version 4.5.1 with the "Command Line Tools" installed. I installed ghc from the haskell-platform after updating the os x and xcode (and command line tools). -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7359> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
