 I've looked through some other tickets and tried installing libffi5,
 though in my distro (Kubuntu 13.10 x86-64) only libffi6 is available. Even
 after installing that I get the following:
 {{{
 $ ghci
 GHCi, version 7.6.3: http://www.haskell.org/ghc/  :? for help
 ghc: panic! (the 'impossible' happened)
   (GHC version 7.6.3 for x86_64-unknown-linux):
         interactiveUI:setBuffering2

 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
