using botspotter include

there's a site called botspotter, pm me for the link, that keeps track of who, what and when spyders come to your site by adding a php include in the page you want monitored. you then go to their site login and check. I tried this with index.php for phpbb and I got this error:

Warning: Failed opening './botspotterphp' for inclusion (include_path='.:/usr/local/lib/php') in /homepages/34/d87885992/htdocs/index.php on line 29

I made this page called botspotter.php:

<?php// Script Date: 09 Jan 2004
// your botspotter login name
$bsName = 'khisanthax';

// change nothing below this line
function getURI() {
global $HTTP_SERVER_VARS;
$url = '/';
if ( !empty($HTTP_SERVER_VARS['PHP_SELF']))
$url = $HTTP_SERVER_VARS['PHP_SELF'];
elseif ( isset ( $HTTP_SERVER_VARS['SCRIPT_URI']) && !empty($HTTP_SERVER_VARS['SCRIPT_URI']))
$url = $HTTP_SERVER_VARS['SCRIPT_URI'];
if ( isset( $HTTP_SERVER_VARS['QUERY_STRING'] ) && $HTTP_SERVER_VARS['QUERY_STRING'] != "")
$url .= '?'.$HTTP_SERVER_VARS['QUERY_STRING'];

return $url;
}//function getURI()

function getPageStatus() {
global $HTTP_SERVER_VARS, $HTTP_ENV_VARS;
if (isset($HTTP_ENV_VARS['REDIRECT_STATUS'])) return $HTTP_ENV_VARS['REDIRECT_STATUS'];
else if (isset($HTTP_SERVER_VARS['REDIRECT_STATUS'])) return $HTTP_SERVER_VARS['REDIRECT_STATUS'];
else return '200';
}//function getPageStatus()
$status = getPageStatus();
$url = 'http://www.pcpropertymanager.com/botspotter/accept.php'
. '?server=' . urlencode( $HTTP_SERVER_VARS['SERVER_NAME'])
. '&uri=' . urlencode( getURI())
. '&agent=' . urlencode( $HTTP_SERVER_VARS['HTTP_USER_AGENT'])
. '&ip=' . urlencode( $HTTP_SERVER_VARS['REMOTE_ADDR'])
. "&account={$bsName}"
. '&status=' . $status;

$fp = @fopen($url, "r") or die ("\n<a href='http://www.pcpropertymanager.com/botspotter/home.php' target='_blank'>Botspotter</a> <a href='{$url}'>disabled</a>\n");
if ($fp != false) {
fpassthru($fp);
fclose($fp);
}

$url = 'http://www.pcpropertymanager.com/botspotter/accref.php'
. '?server=' . urlencode( $HTTP_SERVER_VARS['SERVER_NAME'])
. '&uri=' . urlencode( getURI())
. "&account={$bsName}"
. '&ref=' . urlencode($HTTP_SERVER_VARS['HTTP_REFERER']);

fclose(fopen($url, 'r'));
?>

and added this line to the top of index.php:

include($phpbb_root_path . 'botspotter'.$phpEx);

can anyone tell me what I need to do to make it work right?
