Comment(by kazu-yamamoto):

 GHC head has already workaround for this. Please see
 libraries/base/GHC/Event/Manager.hs. You can find "#if
 defined(darwin_HOST_OS)".

 But we still have two problems:

  - Building GHC on Mac sometime fails. We need to understand whether or
 not this is due to the new IO manager. Unfortunately, I cannot "make
 install" GHC head at this moment as I described in ghc-deps.

  - We need to rescue old MacOS. http://www.haskell.org/pipermail/ghc-
