I've lost the state in /var for my entire pkg tree on one box that
hasn't been backed up properly in too long.

How can I go about recovering from this?   

/usr/pkgsrc is OK, and there are even some work.arch
directories with completed makes, and bunches of distfiles

/usr/pkg is OK, so there are lots of of installed things
which just work.

Unfortunately, I also have several packages which also got nuked
(those installed in /usr/X11R6, essentially) which rely upon packages
which are installed and working, but about which pkg_* knows nothing.  -:(

What should I do?
