Well, if you know which ports were installed, and if the installed
ports correspond to the versions in your ports tree, and if both
make.conf and /var/db/ports are intact (a lot of ifs here ...), you
can reconstruct it by running :

make generate-plist fake-pkg

in the origin of each of the installed ports, which doesn't require
rebuilds.  IF there is cruft left in /var/db/pkg, then you need to do
this with FORCE_PKG_REGISTER=yes, or empty /var/db/pkg first.
