Comment (by jmr at macports.org):

 This actually seems to apply to all actions. The relevant code is
 [http://trac.macports.org/browser/trunk/base/src/port/port.tcl#L2580
 here]. `process_cmd` always returns 0 regardless of the action's return
 status, unless you've used the -x option. There is however a magic -999
 status code that makes it break immediately.
