Instead of doing this in Makefile, do it in pkg-plist:
@unexec if cmp -s %D/etc/barnyard2.conf.sample %D/etc/barnyard2.conf;
then rm -f %D/etc/barnyard2.conf; fi
etc/barnyard2.conf.sample
@exec if [ ! -f %D/etc/barnyard2.conf ] ; then cp -p %D/%F
%D/etc/barnyard2.conf && chmod 600 %D/etc/barnyard2.conf; fi
