 # We need to teach symon about mbstat changes/removal in r253351 and r253361.
 	@${RM} ${WRKSRC}/platform/FreeBSD/sm_mbuf.c
 # We need to teach symon about pf API changes from FreeBSD 15 onwards.
 
 # Until someone can update sm_pf.c to use the nvlist variants, remove it
 # from FreeBSD 15 installs, as it no longer works due to the removal of
 # DIOCGETSTATUS. Patches welcome!
 # See https://lists.freebsd.org/archives/freebsd-pf/2023-April/000345.html
 # Subject: pf: remove DIOCGETRULE and DIOCGETSTATUS
