Comment (by arno@…):

 Rather than creating a temporary tarball, why not compress in place?
 afsctool (available in ports, though it points to old site information
 that should be updated to https://brkirch.wordpress.com/afsctool/) can do
 this or I'd think you'd be able to use ditto as well. If ditto can't use
 the same source and destination I think it'd be simple enough to rename
 each file as $file.hfscompression and then use mv to replace the
 uncompressed version.
