If you both need to manipulate part of the page and need a specific module,
probably this:
// If we haven't already started loading the module, start loading it:
mw.loader.using('mediawiki.util', function() {
// Module is loaded, *but* it's possible the page HTML is not done. Wait
for it:
$( function() {
// Now it should be safe to do everything:
mw.util.addPortletLink(....);
} );
});
I kind of wish we had a per-user version of the Gadgets interface, in which
case you could pre-declare the dependency more easily. :) Something to
think about for later...
