While waiting for the pic's, might it be the case that the derailer was bolted to the frame with the pivot tab in front of the frame's hanger tab? The tabs are roughly below the derailer's attachment to the frame, and the derailer's tab should be behind the frame's tab to pivot the derailer back and create tension in the chain.
Is the chain routed through the derailer cage properly? Does the chain wrap around (behind and over) the rear wheel sprockets? If the rear wheel was removed, this last detail is not a given.
Lastly, one of the derailer's pivot springs may have broken. No too uncommon.
