ga-outbound-track.js

(function($, window, document){

$(document).on('click', 'a[href^=http]', function(e){

    var $this = $(this)
        ,url = $this.attr('href')
        ,newtab = ($this.attr('target') === '_blank' || e.metaKey || e.ctrlKey)
        ;

    window._gaq = window._gaq || [];
    
    try {

        window._gaq.push(['_trackEvent', 'Outbound Links', e.currentTarget.host, url, 0]);
        
        if (!newtab) {

            e.preventDefault();
            setTimeout(function(){
                document.location = url;
            }, 100);
        }
    } catch (err){}
});

})(jQuery, this, this.document);

This can be placed anywhere (even outside domready) as long as jquery has loaded

if you aren't using relative paths for internal links, consider adding a class="external" to the external links and use that as the selector
