angular-cli, lots of "Module not found: Error: Can't resolve" on initial integration

I've started with a blank angular-cli project (versions below), followed the Angular CLI configuration ( Webpack ) instructions to install jquery and modify angular-cli.json. On ng serve I get the following errors:

[dhaskin@six val2 (ngSemantic %=)]$ ng serve

webpack: bundle is now VALID.
