   3 # the latest runtime
   4 # if this fails we look in the local source cache if they have been fetched
   5 # for an earlier build and compare those MD5 files
   6 # if this fails, we fetch the stuff from online and store it in the local src
   7 # cache.
   8 # The local cache has to be set (makepkg.conf) AND it has to be writable
