/var/db/pkg is empty!

[David J Brooks]

I'm not sure how it happened, but my /var partition was scrambled pretty 
badly, and now my /var/dbpkg and /var/db/ports directories are empty... which 
causes portversion and portugrade to produce the following messages:

> portversion
** No matching installed package: *

>portupgrade -a
** No such installed package: *

Is there a way to rebuild the ports database so that these will work properly?
