Fifth, don't install that package at all.  OpenSSH versions prior to 2.3.0
have known, and widely publicised, security issues.  There is even a 2.5.1
version now ... if you're installing SSH go with 2.5.1.

http://www.openssh.com/security.html:

    A buffer overflow in the CRC32 compensation attack detector can lead to
    remote root access. This problem has been fixed in OpenSSH
    2.3.0. However, versions prior to 2.3.0 are vulnerable."
