Import susy in Ember application

Have you tried to include Susy in your Ember application? I have tried it with different approaches but they don't work.

• Install susy as npm module using npm install susy.
• Install susy with the ember-cli.
• Install susy and use eyeglass.

The build finishes ok but there is a problem with the import (it is not importing the susy file). I'm trying the options below:

@import 'node_modules/susy/sass/susy.scss'

@import '../../node_modules/susy/sass/susy.scss'
@import 'susy' (with eyeglass)

Have you run into the same issue before?

Thanks in advance
