 I imagine it has been going on as long as you've installed the ports that
 provide those unreadable files:

 {{{
 $ port provides /opt/local/libexec/dbus-daemon-launch-helper
 /opt/local/libexec/ssh-keysign /opt/local/bin/cdda2wav
 /opt/local/bin/cdrecord /opt/local/bin/readcd /opt/local/sbin/rscsi
 /opt/local/libexec/dbus-daemon-launch-helper is provided by: dbus
 /opt/local/libexec/ssh-keysign is provided by: openssh
 /opt/local/bin/cdda2wav is provided by: cdrtools
 /opt/local/bin/cdrecord is provided by: cdrtools
 /opt/local/bin/readcd is provided by: cdrtools
 /opt/local/sbin/rscsi is provided by: cdrtools
 }}}

 For each file, it can either be considered a bug that they are not world
 readable, or else possibly it is intentional. You would have to ask the
 developers of those programs. Cc'ing Marcus who maintains dbus.

 If there is a base bug here at all, it is that "sudo port rev-upgrade",
 though invoked as root, drops privileges and therefore cannot read files
 that are not world-readable.
