so there's no checksum file.
I changed the following from the PR submission:
@ Removed files/ dir completely, all it contained was an empty md5 file
and author's comments (keep that on your machine please :)
@ Added "/usr/bin/perl" in front of pkg/INSTALL in post-install, so
it will work even if the user doesn't get the file over a permission-
preserving medium (e.g., ftp)
@ I think that's all.
