<embarassed>OK -- I was missing a script or two</embarassed>

So now I've locked and loaded the following:

class Page_Controller extends ContentController {
	public static $allowed_actions = array(
	);

	public function init() {
		parent::init();
		Requirements::javascript(THIRDPARTY_DIR.'/jquery/jquery.min.js'); //include jquery bundled with ss
		Requirements::javascript('themes/'. SSViewer::current_theme() .'/javascript/lightbox.js'); //link to js file in current theme folder
		Requirements::javascript('themes/'. SSViewer::current_theme() .'/javascript/effects.js');
		Requirements::javascript('themes/'. SSViewer::current_theme() .'/javascript/prototype.js');
		Requirements::javascript('themes/'. SSViewer::current_theme() .'/javascript/scriptaculous.js');
		Requirements::javascript('themes/'. SSViewer::current_theme() .'/javascript/builder.js');
	}
}

I now have two instances of builder.js and effects.js showing up -- but lightbox still isn't working... ?

Any luck getting it to work?

If you're still having issues, I would try limiting your Requirements to just the files you need for the lightbox to work (which i'm guessing are jquery.min.js and lightbox.js).

Some other considerations:

1. Are you also firing a script to initialize the lightbox? (assuming lightbox.js is a js library).
2. Do you have the correct css class on your links in the template?
3. When you click a link that is suppose to open a lightbox, are there any errors in firebug/chrome developer tools?
