Comment (by ctreleaven):

 @cave-canem, is there some particular reason you are using a compiler not
 specified in the port?

 The build logs for dav1d 0.9.1 are available for now.  The main.log for
 the OSX 10.9 builder is at
 https://build.macports.org/builders/ports-10.9_x86_64-builder/builds/155679/steps
 /install-port/logs/main.log

 The configure phase starts with:

 {{{
 :notice:configure --->  Configuring dav1d
 :debug:configure Preferred compilers: clang macports-clang-9.0 macports-
 clang-8.0 macports-clang-7.0 macports-clang-6.0 macports-clang-5.0

 :debug:configure Executing org.macports.configure (dav1d)
 :debug:configure Environment:

 }}}

 When linking the libarary, it does include the directive '-install_name
 @rpath/libdav1d.5.dylib'.  Unfortunately, I'm unable to find build logs
 for dav1d 0.9.0 to see if this has changed.

 On the 10.9 builder, meson throws the following WARNING/error:
 {{{

 }}}

 The 10.14 build log does not have such a report.  I don't know much about
 meson internals but I would guess this is where the difference occurs.
 I'll check for this error on the 10.10, 10.11, etc builders.
