How to create Omega 4 subtheme with new "default" libSass based starterkit? I am trying to install omega 4, now at 4.4, which uses liBsass for the default starterkit. 
How do I proceed about this - I understand I need now npm and gulp instead of the previous Ruby stuff required for Omega 4.3?
Everything installs fine, but drush omega-guard complains about gemfile (which it should not use, as I understand).
I've had a lot of problems getting started with the new starterkit. It seems to me as if omega-guard does not yet support the new kit. You can still accomplish the same by running gulp in the subthemes directory. This will start the gulp watching process in foreground.

For more information about gulp and the libSass starter kit, I can recommend this post: https://www.drupal.org/node/2537364#comment-10287771
