Porters: please make sure you use bsd.port.mk 1.75 or later when
updating ports. That version of the makefile adds all sums. Previous
versions of the makefile will still work for people installing ports.
use BSD install programs, not cp; mktemp -> mkstemp;
setreuid -> setuid; update packing list; don't
even try to build a package as it won't install
correctly
