After this message I took a better look and discovered I made a one line 
mistake when updating the port.

This very patch did not apply cleanly, so I replayed it by hand, and in 
doing that I skipped removing one line of code, that was causing your issue.

I have just pushed a commit fixing this error:

https://cgit.freebsd.org/ports/commit/?id=32c43c505242463fb127845d0208ecf345124d13

Luckily the error looks actually unharmful apart fro the warnings being 
logged.

Thanks for pointing the issue here, would have not noticed otherwise.
