wesnoth @1.16.6 +debug: linking error: udefined symbols for architecture x86_64

I noticed rev-upgrade wanted to rebuild it (edit: I think due to a change in which python variant I had boost176-numpy installed with) but couldn't due to being stopped by another failing port, so I tried rebuilding manually and got this error:
