Comment (by ryandesign):

 Replying to [comment:6 l2dy]:
 > We can merge the Travis configurations (in a new commit, not git-merge),
 but I'd suggest creating a new bintray account for uploading (currently
 using `l2dybot`). Travis CI supports deploying tags only: https://docs
 .travis-ci.com/user/deployment/#conditional-releases-with-on.

 I don't understand the issues you're talking about, but we do have a
 "macports" account at Bintray that's not currently being used for
 anything.
