Page controller doesn't work

[GoogleCodeExporter]

Minify version: 2.1.2
PHP version: 5.2.8

What steps will reproduce the problem?
1. Minify a HTML page with the Page controller.
2.
3.

Expected output: Some HTML

Actual output: Exception that Mimify_CSS can't redeclared

Please provide any additional information below.
If I change the method loadMinifier in Minify_Controller_Page that it uses
require_once instead:
    public function loadMinifier($minifierCallback)
    {
        if ($this->_loadCssJsMinifiers) {
            // Minify will not call for these so we must manually load
            // them when Minify/HTML.php is called for.
->            require_once 'Minify/CSS.php';
->            require_once 'Minify/Javascript.php';
        }
        parent::loadMinifier($minifierCallback); // load Minify/HTML.php
    }
the exception goes away.
