KoGrid Does Not Work with Gulp and JSPM-GitHub

While building a project with JSPM-GitHub and KoGrid, I receive the following error message:

Error on fetch for github:Knockout-Contrib/KoGrid@2.1.1.js at file:///C:/Users/*/node_modules/jspm-github/Knockout-Contrib/KoGrid@2.1.1.js
Loading app/startup.js
Error: ENOENT: no such file or directory, open 'C:\Users*\node_modules\jspm-github\Knockout-Contrib\KoGrid@2.1.1.js'

The JSPM config.js file that is being used contains the following:

The relevant portions of the config.js file are:

paths: {
"github:": "node_modules/jspm-github/"
},
map: {
"koGrid": "github:Knockout-Contrib/KoGrid@2.1.1"
}

Then, if I change this file to a packages directory that is part of my application, thus:

map: {
"koGrid": "packages/koGrid/koGrid.js"
}

I get a different error with the CSS file since I am also using SystemJS-Plugin-CSS:

Error on fetch for packages/koGrid/koGrid.js/dist/KoGrid.min.css!nm:systemjs-plugin-css/css.js at file:///C:/Users//packages/koGrid/koGrid.js/dist/KoGrid.min.css!file:///C:/Users//node_modules/systemjs-plugin-css/css.js
Loading app/startup.js
Error: ENOENT: no such file or directory, open 'C:\Users*******\packages\koGrid\koGrid.js\dist\KoGrid.min.css'

Perhaps I'm doing something wrong with this, but perhaps the structure of this repository needs to be updated.
