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