51 | # To fix dependency ordering, on *nix systems, edit Makefile.SH to create a |

57 | # The basic logic is: |
58 | # 1) if there's a Makefile.PL in git for the module, use it. and call make | |
59 | # 2) If not, auto-generate one (normally) | |
60 | # 3) unless the auto-generation code figures out that the extension is | |
61 | # *really* simple, in which case don't. This will be for pure perl | |
62 | # modules, and all that is needed to be done is to copy from the source | |
63 | # to the dest directories. | |
