Comment:

 Thanks for pointing out this regression. I've updated the patch to apply
 to ''extract_archive_to_tmpdir'' instead of ''_activate_file''. This way
 ditto can compress the entire directory tree of a port, which is a lot
 faster and seems to preserve hard links. I've also tried to hook the HFS
 compression directly into the unarchiving pipe, e.g. {{{bsdtar -cpf -
 --format cpio @${location} | ditto -xV --hfsCompress - $extractdir}}}, but
 it turned out that the conversion from tar to cpio does not preserve hard
 links https://github.com/libarchive/libarchive/wiki/Hardlinks.
