Have you tried sysutils/portmanager?
From the man page:
" Determines ports that are out of date by comparing them to Makefiles
downloaded through cvsup into the ports tree"
So it looks like it doesn't require /var/db/pkg to work.
"-p or --pristine
Updates a port if any dependency in it's /var/db/pkg/{port
name}/+CONTENTS does not match what is installed. The effect
is when
a port is updated, any port who uses the updated port in it's
depen-
dency chain, no matter how deep, are rebuilt. Normally only
ports one
level up are rebuilt."
This looks like it rebuilds /var/db/pkg
You also probably need -f if your ports are up-to-date
I haven't tried it in these particular circumstances and I'm not sure if
I've read the man page right but it's worth a try, it's a pretty clever
utility.
Note if you try it on a single port you have to put the options after
the port name, see the EXAMPLES section. Also see my recent question
about portmanager and /tmp if you are rebuilding lots of ports in one
session.
