require(string_native.lib.php) fails

[Chip Marshall]

I get the following AJAX error when attempting to perform SQL queries via Chive:

2010/04/09 13:19:45 [error] [php] require(string_native.lib.php) [<a href='function.require'>function.require</a>]: failed to open stream: No such file or directory (/usr/home/vweb/2bithacker.net/donate/chive/protected/extensions/sqlquery/libraries/string.lib.php:39)

FreeBSD 6.2-RELEASE i386
Server: Apache/2.2.4 (FreeBSD) mod_ssl/2.2.4 OpenSSL/0.9.7e-p1 PHP/5.2.4

Appears to only be included by protected/extensions/sqlquery/libraries/string.lib.php in the following block:

/**
 * Load proper code for handling input.
 */
if (defined('PMA_MULTIBYTE_ENCODING') || $GLOBALS['PMA_allow_mbstr']) {
    $GLOBALS['PMA_strpos'] = 'mb_strpos';
    $GLOBALS['PMA_substr'] = 'mb_substr';
    require 'string_mb.lib.php';
} else {
    $GLOBALS['PMA_strpos'] = 'strpos';
    $GLOBALS['PMA_substr'] = 'substr';
    require 'string_native.lib.php';
}
