Nette a Kdyby/Doctrine – ‚doctrine.default.metadataDriver‘ not found

Ahoj všem,
rád si hraju v nette a chtěl jsem si osahat a posunout se zase o kousek dál. Chtěl jsem se seznámit s Doctrinou (pomocí Kdyby/Doctrine) a přes všemožné googlení jsem vždy skončil s hláškou:
Nette\DI\ServiceCreationException
Class Doctrine\Common\Persistence\Mapping\Driver\MappingDriverChain used in service ‚doctrine.default.metadataDriver‘ not found.

Budu moc rád za každou radu a nakopnutí, páč pro oči už nevidím:-/
Moc děkuju

Pro pořádek ještě uvádim:
