I had 'port' use the defaults for compiler & other settings, and with a small tweak to the Portfile the port builds correctly now. I'll do a PR for this fix soon-ish.

If you're going to help out with keeping older systems alive in MacPorts, that would be great. I can bring you up to speed on how MacPorts works behind the scenes.

But you have to be very facile at forcing different compilers as I showed you. 

A very great amount of software no longer builds with MacPorts default compilers on these old systems, and you have to try different ones.  Don't have any expectations that things will go smoothly for updates. There are only a half-dozen of us who work on this, or less, and many ports may not have been tested.

gcc6 and clang-3.x are usually your go-to compilers when the default doesn't work.



We appreciate the help!!
