Comment (by ryandesign):

 The request to have mpbot use mpbb-list-subports is #57563. However, I may
 not be understanding:

 Replying to [comment:1 l2dy]:
 > `mpbb` checks for "already built" packages, which is not desired on
 Travis CI.

 By what means are we currently ensuring that prebuilt archives are not
 used on Travis? I don't see that happening. I remember within the past
 couple months we had a PR submitted which made a change to a port that
 made it unbuildable, but because the port's version and revision were not
 changed, Travis successfully downloaded the previously-built archive and
 reported a successful build, so the PR got merged. (I don't remember what
 port it was and can't find that PR again now.)

 Or, is that what this PR is about? That we ''want'' Travis not to check
 for preexisting archives, but it's not currently programmed to do that? If
 so, then using mpbb-list-subports with empty --archive-site parameter
 should be the solution.
