Building ports as root is a rare thing these days, most build tools
build everything as a regular user (most of the time, nobody) so
ownership of files in distribution files is not retained anyway.

To set user/group/mode ownership in the resulting packages, you need to use
the @user, @group and @mode keywords in the pkg-plist file. (or the @
keyword if one file needs a specific user/group/mode.) See:
