Por algum motivo não está indo completo…

Por algum motivo não, vc tá usando o plugin do vraptor do Jpa.
Você ao menos leu a documentação do mesmo ?
Provavelmente não, porque ela diz isso.
"O plugin VRaptor JPA cuida da criação e injeção de depedência da EntityManager e EntityManagerFactory.
Além disso, o plugin aplica o padrão Open EntityManager In View, isto
é, ele abre uma transação com o banco de dados no ínicio da requisição e
executa o commit da transação no fim da requisição."
E ainda assim, eles tem o código do mesmo no github, e essa classe também tem um produces igual o seu.

Ai quando vc pede um entity manager, o cdi não tem como adivinhar qual ele vai injetar, por isto da exception, e você tem anotações de @Default, @Alternative, que é para algumas situações.
