Comment (by g-raffy):

 While this gets fixed, I managed to get around this bug by replacing
 `-DBUILD_PROTOBUF=NO` with `-DBUILD_PROTOBUF=YES` in
 `/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/graphics/opencv/Portfile`,
 then rebuilding opencv :
 {{{#!bash
 sudo port clean opencv
 sudo port install opencv +contrib+java+python27+python36+qt5
 }}}

 Before doing so, make sure protobuf3-cpp is installed so that you have the
 command `protoc` to generate the headers compatible with your protobuf
 library version:
 {{{#!bash
 sudo port install protobuf3-cpp
 }}}

 Hope this helps
