installing unsigned packages

This is current/amd64. I just build the rsync package
as currently tweaked for xxhash, up to make package;
now I'm trying to install it.

$ env TRUSTED_PKG_PATH=/usr/ports/packages/amd64/all/ make update
===> Updating for rsync-3.2.7p0
Upgrading from rsync-3.2.7

file:/usr/ports/packages/amd64/all/rsync-3.2.7p0.tgz: unsigned package
Can't find /usr/ports/packages/amd64/all/rsync-3.2.7p0.tgz
Couldn't install rsync-3.2.7p0

Isn't TRUSTED_PKG_PATH supposed to enforce pkg_add -Dunsigned?

Also, "Can't find /usr/ports/packages/amd64/all/rsync-3.2.7p0.tgz"
seems odd as the file exists.
