Test Plan

poudriere testport: ok on 11amd64
portlint: looks ok

Note that on FreeBSD systems older than 10.3 RELEASE get the following build warning:
remmina/src/remmina_file.c:642: undefined reference to utimensat
cc: error: linker command failed with exit code 1 (use -v to see invocation)

This is because utimensat was only added to FreeBSD's libc in 10.3 RELEASE.
I am working on a patch to resolve this.

Reason for review: I have never deleted a port before, and I would like to check this diff includes the necessary items for a port removal (plus it is not part of my implicit approval for "things I have done many times before").

Approved.

When ports get removed, it is possible that, depending upon which tools people use to manage their ports, that the old port may still be installed. If that doesn't cause any problems, then you're good to go. If you need to be sure that people have uninstalled the old port (such as another port now installs those files), you should also add a note into UPDATING when you commit this.
