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