It's not a buildbot issue at this point; it's a MacPorts base issue. MacPorts base needs to offer portfiles the ability to specify that a port cannot build on a particular platform. It has been previously mentioned that the existing `platforms` option could be extended with a syntax like:

platforms {darwin >= 7}

but I don't think any work has begun on that.

We would then probably need a new MacPorts action, maybe "installable", that lets a user (or more particularly the buildbot) query whether MacPorts thinks a port is installable or not. If not, the buildbot can then skip it.

I couldn't immediately find a ticket for this.

Yes, our buildbot configuration is on GitHub, as is the source of mpbb, the tool our buildbot runs to do MacPorts builds.
