It appears that Horde requires the "domxml" PHP extension, which is apparently not a part of the standard CentOS 4.x PHP 4.x distribution. In fact, "domxml" is no longer available from the sourceforge web site as they prefer the use of the dom libraries in PHP5 instead.
http://pecl.php.net/package/domxml
Given these facts, how has anyone gotten this working? I would love to replace Squirrelmail with IMP if it can be made to work without lots of customization.

You need the domxml PHP extension to use the configuration tool.
