It only takes about a pint to lube the engine. I'd think if they spun bearings on a fresh build they screwed something up. Not primed, not properly lubed on assembly or maybe the wrong assembly lube was used. Of course there could have been improper clearances or other mechanical faults.
Even a quart low on a stationary engine shouldn't be a problem.
