couldn't you do something like this?
1) install all your "big" ports (leafs with lots of dependancies)
2) run this to get a list of depedancy ports which should already be
there, just not in /var/db/pkg
# pkg_info -ar | awk '/Dependency:/ {print $2}'|sort|uniq
3) "install" these ports so that they get added to /var/db/pkg.
Seems like this should work, am I missing something?

Thanks. Good ideas. I'll play with this when I have time. But after
using mtree to recreate the structure in /var (off the / filesystem),
things came back online pretty well. I'll most likely get things put
back together and then just recreate the /var filesystem and copy
everything back into it.

I'm presently doing this now. I have reinstalled most, if not all, top
level ports and will be running through `pkgdb -F` tomorrow. I suspect
that will take a fair amount of time.
Thanks.
