Webmin not found

When I try to install Virtualmin Pro, I get the following error. I am installing to a fresh Debian 4.0 server.

Welcome to the Virtualmin Professional installer, version EA4.2

WARNING: This is an Early Adopter release.

The installation is quite stable and functional when run on a freshly
installed supported Operating System, but upgrades from existing .wbm-
based systems, or systems that already have Apache VirtualHost
directives or mail users, will very likely run into numerous problems.
Please read the Virtualmin and Early Adopter FAQs before proceeding if
your system is not a freshly installed and supported OS.

This script is not intended to update your system. It should only be
used to install Virtualmin Professional, or to upgrade a Virtualmin
GPL system that was installed manually via .wbm packages. If you have
previously installed Virtualmin via this script or the GPL version of
this script, upgrades and updates should be handled within Virtualmin
only.

The systems currently supported by our install.sh are:
Fedora Core 3-6 on i386 and x86_64
CentOS and RHEL 3-5 on i386 and x86_64
OpenSUSE 10.0 on i586 and x86_64
Mandriva 2007 on i386
Debian 3.1 and 4.0 on i386 and amd64
Ubuntu 6.06 LTS on i386 and amd64

If your OS is not listed above, this script will fail and attempting
to run it on an unsupported OS is not recommended, or supported. The
recommended operating systems for Virtualmin Professional, and more
details about them, can be found here:
