Next steps to find the cause of Ember-CLI/Broccoli Plugin error during build

Question

This happens on a Win 8.1 PC, as a result of "ember serve", with no modifications done after an error free, ember new MyApp.

From my research:

"Error: EPERM: operation not permitted, symlink" means that there is a permissions issue.
So I made sure my Windows 8.1 local security policy is set to admin and I'm running my cmd window with admin privileges. I've also reinstalled and updated Ember-CLI and NPM, globally. I'm not sure what else to try.

Also, the build is very slow, over 5 minutes on a normally fast PC. I have ember-cli-windows installed and it's still very slow.

Editorial comment: This seems like a pretty big fail for a "system" fresh out of the box. If it's this buggy without even adding new code... maybe I should invest time with Angular 2.0?
