Travis CI timeouts for MacPorts builds

Tries being the operative word here. ;-)

I'm guessing that "we" means the devs who maintain the build config. If
I can assist, let me know, but I don't think it likely at this point.

At a glance, I'd expect a glib2 build from source to be quite a drag.
The various xorg-* ports might also take some time. I don't see why the
latter would be required, given that the build apparently did not use
the +emacs variant?

If you ignore Travis results, why run Travis CI in the first place? I
suggest to either fix the underlying issue or remove Travis builds. That
would at least free up some server resources, for the benefit of other
projects which actually rely on their Travis builds.
