aurelia publishing and installing components via jspm and github - aurelia

Question

I am trying to figure out how to publish and install components for aurelia via jspm and github.
I have a test component at:
https://github.com/caperavensoftware/pragma-tabsheet
I created a new project and install this component via jspm as:
jspm install pragma-tabsheet=github:caperavensoftware/pragma-tabsheet
in my welcome view I require and use it
<template>
<require from="pragma-tabsheet"></require>
<h1>Welcome</h1>
<pragma-tab-sheet>
<div id="tab1" data-tab="Tab 1"><h2>Tab 1</h2></div>
<div id="tab2" data-tab="Tab 2"><h2>Tab 2</h2></div>
<div id="tab3" data-tab="Tab 3"><h2>Tab 3</h2></div>
</pragma-tab-sheet>
</template>
But when running it i get a error where the controls template is not being loaded from the right path.
GET http://localhost:8080/jspm_packages/github/caperavensoftware/pragma-tabsheet#master.html 404 (Not Found)
Looking a the networks tab in chrome debugging the javascript files are loading correctly but the aurelia template is not.
Any ideas on what I am doing wrong here?
I also tried adding it as a plugin:
export function configure(aurelia) {
return new Promise((resolve) => {
aurelia.use
.standardConfiguration()
.developmentLogging()
.plugin('pragma-tabsheet');
aurelia.start().then(() => {
aurelia.setRoot();
resolve();
});
});
}
but that did not resolve the problem.
