AF_PACKET code is guarded by HAVE_NETPACKET_PACKET_H which is defined by
AC_CHECK_HEADERS(netpacket/packet.h) in configure.ac. If you have the file
under /usr/include, /usr/local/include or somewhere else that CPPFLAGS
or CFLAGS points to then you may want to override the check via
CONFIGURE_ENV+=ac_cv_header_netpacket_packet_h=no in Makefile.local for
just lang/python* or in /etc/make.conf for all.

netpacket/packet.h appears to be provided by libc package only on Linux.
If you don't want to a assume pilot error then try bisecting the host
environment against a pristine jail until you get can narrow down the
steps to reproduce worth for a bug report.

Why not contact the maintainer instead of suggesting possibly incorrect fix?
