patch to fix the problem
This patch file was missing updating to 2.8.1. It fixes the pkg build problems.
Build and package info is available at https://gitlab.com/swills/freebsd-ports/pipelines/266527516
I can confirm that your patch fixes the compilation issue.
From my point of view the port is ready to commit ;-)
