Unlike the CI systems used for PRs, which we don't own, builds can take
as long as they need to on our buildbot. (There is a timeout if the
build produces no output for hours, but that isn't usually an issue.)

Assuming a port builds on a given platform, binary availability is
purely a matter of licenses. Normally you could inspect the build logs
at <https://ports.macports.org/port/blender/builds> to see why binaries
were not uploaded, but in this case there was no build because of a
GitHub webhook delivery failure.

I redelivered it and the builds should be happening soon.
