Is there a way to update to OpenSSH 5.9 from OpenSSH_5.6p1 on a MAC?

Question

There are certain security holes that are apparently filled in OpenSSH 5.9. I tried downloading the openssh-5.9.tar.gz file from the openssh website, but i have no idea how to use the source code to update the version on my mac(10.7.3). Is this doable or is it something that apple will need to update when releasing the next version of lion?

  ssh -v
OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011
usage: ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]
           [-D [bind_address:]port] [-e escape_char] [-F configfile]
           [-I pkcs11] [-i identity_file]
           [-L [bind_address:]port:host:hostport]
           [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]
           [-R [bind_address:]port:host:hostport] [-S ctl_path]

install macports, a system for installing and upgrading software packages on OSX (http://www.macports.org). Then just "sudo port install openssh"

The ports openssh will be installed in /opt/local/bin.
