Comment (by FlyingSamson):

 Upstream is now pulling in protobuf 26.1.

 I guess this is why, in [https://github.com/macports/macports-
 ports/pull/19665 PR 19665], grpc was made to fetch its own protobuf
 followed by a post-destroot clean up step to remove files that conflict
 with a macports-installed-version of protobuf.

 I'm currently trying to bring protobuf to this version to revive
 [https://github.com/macports/macports-ports/pull/21170 PR 21170]. Maybe
 this will allow using macports own protobuf instead of one that conflicts
 with it.

 I don't quite understand in which sense above mentioned
 [https://github.com/macports/macports-ports/pull/19665 PR 19665] is
 dependent on the tensorflow port though.
