#63613: port install: fetch shouldn't abort the whole command on a 503 error
-------------------------+--------------------

-------------------------+--------------------
 I have no idea why I'm getting 503 errors from `packages.macports.org`,
 but IMHO `port` shouldn't immediately die on 4xx or 5xx errors. It should
 instead try the next download location.
