Comment 1 Niclas Zeising freebsd_committer 2020-08-18 15:19:47 UTC
This should have been fixed with ports r545235.  Please let us know if it's still a problem for you.
Comment 2 Kyle Evans freebsd_committer 2020-08-29 00:40:25 UTC
I agree with Niclas' assessment and note that libunwind-20200331_1 is now available in the amd64 repo. Closing as FIXED as nothing further will be done here, but please feel free to re-open if needed.
