Comment:

 In the log I see undefined symbols due to:

 }}}

 One question is: why is the build using the installed libvpx dylib? It
 should be using the just-built libvpx dylib, which will have been built
 for the correct architecture. It's because `-L/opt/local/lib` appears
 before `-L.` in the link line. That's something for Chris to sort out.

 Another question is: why do you have an x86_64 libvpx dylib installed on
 your arm64 Mac? Did you migrate from an x86_64 Mac and not follow the
 [wiki:Migration migration procedure]?
