What’s nice with WP/WPMU is that you don’t need to include the most popular javascript libraries with your plugin, they are already installed (scroll down a bit and you see the list: https://codex.wordpress.org/Function_Reference/wp_enqueue_script ), and using wp_enqueue_script you avoid conflicts.

E.g.: BPDEV-FLICKR should/could do (not tested):

function init_scripts() {

global $bp;

wp_enqueue_script('prototype');

wp_enqueue_script('scriptaculous-builder');

wp_enqueue_script('scriptaculous-effects');

wp_enqueue_script('bpdev-lightbox', bloginfo('wpurl').$bp['flickr']['lightbox'] . 'js/lightbox.js' , array( 'prototype','scriptaculous-builder','scriptaculous-effects' ) );

}

add_action('init','init_scripts');
