Basic adding of angular/material fails with Angular 6

Question

I simply do the following:

ng new my-proj
cd my-proj
ng add @angular/material

I get in response the following error:

Your project is not using the default configuration for build and test. The Angular Material schematics can only be used with the default
configuration

Seriously?? Anyone else?
