Reading https://github.com/mapbox/tilemill/blob/master/servers/Route.bones,
they're using require.resolve() to get the path to the javascript assets.
It's a strange way to find files, isn't it ?
Anyway libjs-wax is a browser only library, and is correctly not on node's modules path,
but it has to be somewhere on the local path of your application, so i think you
can fix your problem by simply adding 
usr/share/javascript/wax usr/whatever/path/to/tilemill/wax
to tilemill debian/links
