 The current Cabal used for building GHC has a small bug, it *always*
 creates
 the data directory, even if there are no data files in the package. Simple
 fix:

 *** /tmp/Install.hs     2007-09-09 14:56:50.000000000 +0200
 --- Distribution/Simple/Install.hs      2007-09-09 12:57:21.000000000
 +0200

 *** 115,121 ****
          (putStrLn ("directory " ++ haddockPref pkg_descr ++
                     " does exist: " ++ show docExists))
     when (dataFilesExist || docExists) $ do
 -     createDirectoryIfMissingVerbose verbosity True dataPref
       flip mapM_ (dataFiles pkg_descr) $ \ file -> do
         let dir = takeDirectory file
         createDirectoryIfMissingVerbose verbosity True (dataPref </> dir)
 --- 115,120 ----



 Nothing substantial, but this leads to lots of useless empty directories
 when
 GHC is installed. Feel free to apply this fix in the right repository...
 (No
 idea which)
