Possible bug in installation (or installation tutorial)

[celineCQ]

Hi,
First of all : thanks for developing superpowers <3
We tried following this intallation tutorial http://docs.superpowers-html5.com/en/development/building-superpowers.
Everything seems to work fine, we get the interface allowing us to start creating our game.
While clicking build however we get the following bug :

SupEngine.js:19691 THREE.WebGLRenderer 81
runtime.js:31 Uncaught TypeError: Cannot read property 'Scene' of undefined
    at Object.createOuterAsset (runtime.js:31)
    at Player.getOuterAsset (SupRuntime.js:1932)
    at Object.lateStart (runtime.js:20)
    at async.each (SupRuntime.js:1906)
    at SupRuntime.js:206
    at Object.async.forEachOf.async.eachOf (SupRuntime.js:258)
    at Object.async.forEach.async.each (SupRuntime.js:234)
    at Player._lateStartPlugins (SupRuntime.js:1903)
    at async.series (SupRuntime.js:1780)
    at SupRuntime.js:743

What are we doing wrong there ?
