swi prolog 7.2.3, but 7.4.1 out, and 7.5.2 dev

[capitalism]

lang/swi-pl seems to be lagging behind. Who's the maintainer?

Is it hard to port?

Ubuntu is too terrible to consider switching too.

 

[talsamon]

whos the maintainer?

The mail address is in the port Makefile. You
can contact the maintainer direct or open a PR with an update
request.
I can provide an inofficial update to 7.4.1.(no guarantee).

Is it hard to port?

Sometimes. But most of the time it's fairly straightforward.
