195,"cabal output changed, breaking Build.hs under some conditions",MtnViewMark,MtnViewMark,"From Chris Dornan:

The current tar-ball generator doesn’t work with the latest cabal-install (0.14.0).

In build.hs we have

   --
   -- Too sleepy. Future: solve this via the cabal library
   --
   let cmd = ""cabal install --dry-run --reinstall "" ++ (
                       intercalate "" "" [ package
                               | (_, package) <- urls
                   ] ) ++ "" > platform.packages.raw""
   --writeFile ""platform.packages.cmd"" cmd
   system cmd
   src <- readFile ""platform.packages.raw""

   let programs = drop 2 $ lines src
   writeFile ""platform.packages"" (unlines programs)

The problem is that ' cabal install --dry-run --reinstall' has become too loquacious for
our convenience and is annotating the output with extra context. The first word
of the output still contains what we need (the package) so I have replaced the
second `let` binding above with this,

   let fw ln    = case words ln of { [] -> """"; p:_ -> p; }
       programs = map fw $ drop 2 $ lines src

to get a sensible content for platform.packages (for a while).
