Just a guess, as I use something similar for opening certain links in a new window, so something like??:

<script type="text/javascript">
    /* <![CDATA[ */
    jQuery(function(){
        jQuery("a[href^='http:']").attr("target", "your_target");
    });
    /* ]]> */
</script>

But you definitely don't want it between php tags.

Have you also put in in the footer? It's still not working.
Mine looks like this now:

<?php
/**
 * This is the footer include template.
 *
 * For a quick explanation of b2evo 2.0 skins, please start here:
 * {@link http://manual.b2evolution.net/Skins_2.0}
 *
 * This is meant to be included in a page template.
 *
 * @package evoskins
 * @subpackage natural_pink
 */
if( !defined('EVO_MAIN_INIT') ) die( 'Please, do not access this page directly.' );
?>

require_js( '#jquery#' );

<script type="text/javascript">
    /* <![CDATA[ */
    jQuery(function(){
        jQuery("a[href^='http:']").attr("target", "content");
    });
    /* ]]> */
</script> 

<!-- =================================== START OF FOOTER =================================== -->

No, I put mine in the header. I'm assuming "Page Speed" has convinced you to move your scripts to the bottom of the page to help parallel downloads. ;)

In your last example, you need to move the "require_js( '#jquery#' )" statement inside the php tags.

Still not working. This is my complete index.main.php

<?php

/**

 * This is the main/default page template.

 *

 * For a quick explanation of b2evo 2.0 skins, please start here:

 * {@link http://manual.b2evolution.net/Skins_2.0}

 *

 * It is used to display the blog when no specific page template is available to handle the request.

You need your require_js( '#jquery#') to come before your header include

That did the trick!!
