EmberJS(without ember-cli) development behind firewall using systemjs or anyother loader

I am planning to use EmberJS for a small application in my day job. I have used a little ember on my laptop using ember-cli. However at work I don't have access to Github. I am planning to download the libraries and start using without any tools like npm, bower. I have tried to setup a static web app at http://ift.tt/1LCnKDy There is not much code in there. I have tried to keep the structure as close to ember-cli as possible, os that it will be easier for me to upgrade to ember-cli when access is availble. I would like to use ES6 modules like in ember-cli. However the fist step of loading the Ember is not working.

Error I see in chrome console is

Error: http://localhost:4200/vendor/ember/ember.debug.js detected as System.register but didn't execute.

Any help to resolve this appreciated. Thanks
