If you have enough time, I would try using pkgfile to recover the
installed packages. I thing something like this should suffice:
# update the pkgfile database
pkgfile -u
# find the package names for all binaries
find /usr/bin -type f -exec pkgfile '{}' ';' | uniq

I assume that the libs would be installed as depends for the programs
that has a binary in /usr/bin
