Object [object Object] has no method 'done'

[pnpetroff]

I'm trying to get imagefill.js to run. I'm using imagesLoaded.js from here: http://desandro.github.io/imagesloaded/imagesloaded.pkgd.min.js

the problem is that when I attach imagefill() to a selector I get:

Object [object Object] has no method 'done'

The line that gives the error is:
$container.imagesLoaded().done(function($img) {

Is imageFill.js not working with the latest imagesLoaded version?
