Jim, I might be wrong, but I seem to recall reading somewhere that the shell the system uses to boot up must be physically present in /bin and not symlinked to somewhere else like /usr/local/bin. The default setup is to have /bin/sh symlinked to /bin/bash. This is supposed to be a security precaution to prevent some random luser from replacing the default shell. As others have suggested, you'll need to boot using your rescue disk to get your system going again.
