Comment (by ctreleaven):

 The build logs for 10.6 through 10.9 all the above warning/error related
 to nm; no such reports are in the 10.10 through 10.12 builds.  All the
 affected builds use:

 {{{
 :debug:configure Using compiler 'MacPorts Clang 9.0'
 :info:configure C compiler for the host machine: /opt/local/bin/clang-
 mp-9.0 (clang 9.0.1 "clang version 9.0.1 ")
 :info:configure C linker for the host machine: /opt/local/bin/clang-mp-9.0
 ld64 127.2
 }}}

 The installation stats for dav1d and ffmpeg both show a non-trivial number
 of installs on systems that are apparently affected.  But there have been
 no other reports of failures.  I don't have access to older systems to see
 if ffmpeg actually fails or not.

 I suppose this could also be a newly introduced problem in meson, as well.
 I note that meson was updated to 0.58.1 a couple of months ago.

 I'm not seeing an obvious way to fix dav1d.  Please let me know if I'm
 missing something.
