Comment (by kakuhen):

 You can select the "CONTINUE" restart when that appears. Unfortunately,
 MacPorts is non-interactive and it is not possible to do so in a Portfile.
 I forgot how I restarted from this error, sorry. But you should be able to
 build locally anyway (or in any environment that lets you select a
 restart).
