  60 # [1] this is a hack for GHC <= 6.10.1.  When making dependencies with
  61 # ghc -M, in GHC 6.10.1 and earlier, GHC needed to find either the .hi
  62 # file or the source file for any dependency.  Since we build the
  63 # .depend files before building the packages, we have to make sure GHC
  64 # can find the source files; hence we have to make sure that the
  65 # import-dirs field of each boot package points to the sources for the
  66 # package as well as the dist/build dir.
  67 #
  68 # In GHC 6.10.2, we changed the way ghc -M worked so that it doesn't
  69 # check for existence of the source file, and doesn't look for the .hi
  70 # file if there is only one possibility for its location.  Which means
  71 # that we must *not* do that above hack in this case, because there
  72 # would be multiple locations to search for the .hi file.
