Maybe installing the files from the live-CD in single-user mode is easier
at this point...

... especially if some crucial files (/usr/bin/csup, /usr/bin/cc, /usr/bin/gcc,
/usr/bin/install, /usr/bin/tar etc...) are missing (and thus preventing csup,
build, install). THEN, with the old /usr/bin/* files reinstalled from media,
source-upgrading with csup / make buildworld etc...  is the way to go.

But ivoras@ is right: restoring /usr/bin is pretty easy nonetheless.
