ssh.postinst: dpkg-statoverride: command not found?

["Ross Smith" <nospam2@pobox.com>]

I've been using ssh 2.3.0 with a stock potato install for a month now, with
no problems.

Now, after running:

apt-get update
apt-get upgrade

I get:

Setting up ssh (2.3.0p1-1.13) ...
/var/lib/dpkg/info/ssh.postinst: dpkg-statoverride: command not found
dpkg: error processing ssh (--configure):
 subprocess post-installation script returned error exit status 127
Errors were encountered while processing:
 ssh
E: Sub-process /usr/bin/dpkg returned an error code (1)

Any suggestions as to how to fix this?
