Created attachment 247906 [details] new port patch The port was prepared to replace devel/grpc142 recently marked broken. Without this port it's not possible to build net-mgmt/fastnetmon and problby other software requiring legacy devel/grpc. Peraps the port should be named devel/grpc-legacy ? It's based on the original devel/grpc142 port and the version number follows Debian devs approach.
Created attachment 247930 [details] new port I found gRPC 1.54.3 to be the last working and prepared port which based mostly on Matthias' work.
I managed to fix the patch for bug 276516 so I am closing this one as obsolete.
