    Yes. If your sources are reasonably up to date (since Jan 23),
    just rebuild it:

    cd /usr/src/secure/lib/libssh
    make clean obj all
    cd /usr/src/secure/usr.sbin/sshd
    make clean obj all install
    cd /usr/src/secure/usr.bin/ssh
    make clean obj all install

    (kill your old sshd daemon, start a new one)

    Verify you are running the new version of the daemon:

% ssh -v localhost
earth:/home/dillon> ssh -v localhost
SSH Version OpenSSH_2.3.0, protocol versions 1.5/2.0.
