The information about files permissions isn't easily recoverable...
With this command (it takes a very long time to run!) you will know wich
programs reinstall:
for i in $(ls -1 /bin /sbin) ; do equery belongs $i ;done | sort | uniq
/tmp permissions are 1777 if I rememeber correctly.
/home is not vital for system sanity, defer its recovery
Mount your system in chroot as if you would install your Gentoo (use the
installation CD and install guide, skipping partitioning, formatting,
bootstrap...!) and rebuild system programs and those listed by the
command above.
Another option, much faster is to skip the equery step, mount the chroot
and:
"emerge -e system"
Other programs complaining about permissions can be restored in a
following phase, from within the running system.
