I attempted two installations of lo on two different hosts with two different
outcomes: one for which the failure is reported above (host A); one on which
the port was successfully installed (host B). For both hosts I attached the
full ports configuration tree.
Host A runs 11-STABLE (rev 365447), host B runs 12-STABLE (rev 360207).
