Horde 3.3.3 fails to work after install

WHEN I INSTALL I GET THIS OUTPUT:
Found ftp://ftp.horde.org/pub/horde/horde-3.3.3.tar.gz in cache ..

The PHP Pear modules Log Mail Mail_Mime DB are required, but Webmin's Pear module is not available to install them - proceeding anyway.
Configuring Apache PHP settings ..
.. already done.

Now installing Horde version 3.3.3 ..

Horde installation complete. It can be accessed at http://MYDOMAIN.COM/horde/. You will need to go to the Setup page under the Administration section to perform further configuration.

More information on using this script can be found at http://www.horde.org/.
The initial administration login is USER.

.. done

Re-loading Webmin ..
.. done

AFTER INSTALL THIS IS WHAT I GET IN THE BROWSER:
