PHP include path error
<p>I keep getting an error when I try to include simpletest in my include_path:</p>

<pre><code>&lt;?
set_include_path(get_include_path() . PATH_SEPARATOR . realpath(basename(dirname(__FILE__)) . '/../../'));

include 'simpletest/autorun.php';
</code></pre>

<p>returns:</p>

<pre><code>.:/usr/lib/php:/Users/kristiannissen/Documents/php
Warning: require_once(/Users/kristiannissen/Documents/php/simpletest/arguments.php): failed to open stream: No such file or directory in /Users/kristiannissen/Documents/php/simpletest/reporter.php on line 13
