Comment (by kencu):

 I can try to work with you on this. It's a big package; looks interesting.
 I downloaded all the components and put them together into a PR. Just
 building it now (on Mojave).

 Off the top, I can see it is setting a deployment target of some macOS
 versions ago, so we'll probably have to deal with that unless there's some
 good reason for it (there usually is not):
 {{{
 MACOSX_DEPLOYMENT_TARGET=10.10 /usr/bin/clang++ ...
 }}}

 You're the maintainer so the Portfile can be however you want it to be,
 but there are certain conventions we usually use and I'll try to massage
 it into those once I have your version up and working. I'll put up a link
 to the PR and we can more easily work on it from there once it's up.

 Trac is OK for working through build issues -- for that, I actually prefer
 it over the GitHub issues list, which is not so easy for me to use for
 issues (although some swear by it). But for this kind of thing -- a
 complicated port upgrade with lots of moving parts -- Trac is not so
 wonderful and I'm glad we moved away from it.

 Keep you posted when I have the PR up. -- Ken
