I think it happened during 11.2-RELEASE → 12.0-RELEASE, but now after removing a package it gives: % sudo pkg_rmleaves diff: unrecognized option `--unchanged-line-format='
Ha, so there are still some people using this port :) This seems to be due to the switch from GNU diff to BSD diff in FBSD 12. I changed the code to use the comm utility instead. See bug #234769 with the port update.
