Comment (by kencu):

 It installed without trouble for me, on 10.14, with the {{{+nonfree}}}
 variant.
 {{{
 $ port -v installed ffmpeg
 The following ports are currently installed:
   ffmpeg @4.3.1_0+gpl2 platform='darwin 18' archs='x86_64'
 date='2020-08-24T17:16:15-0700'

 The specific link line that failed for you did not fail for me:

 So -- it does build, at least some places.

 IF you can live with the default variant, that will get you started, at
 least. Something like this should work for you:

 {{{
 sudo port clean ffmpeg
 sudo port -f uninstall ffmpeg
 sudo port -v selfupdate
 sudo port -v install ffmpeg
 sudo port -v upgrade outdated
 }}}

 Then after you are back in business, try building ffmpeg again with your
 desired variant:
 {{{
 sudo port -v build ffmpeg +nonfree
 }}}
 and if it does build through, then deactive the existing one and install
 the one you want:
 {{{
 sudo port -f deactivate ffmpeg
 sudo port -v install ffmpeg +nonfree
 }}}
