 Replying to [comment:1 ryandesign@…]:
 > 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.

 Can see no reason why MacPorts should complain if a port chooses to
 install files that are not world readable.

 > 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.

 Exactly.

 Since `macports::revupgrade_scanandrebuild` is called after the privileges
 have been dropped (and then elevated for some actions),
 {{{
     if {[getuid] == 0 && [geteuid] != 0} {
         seteuid 0; setegid 0
     }
 }}}
 at the beginning of `macports::revupgrade_scanandrebuild` solves it. Maybe
 the privileges should be dropped again at the end…
