data-integration

olá.
Comprei o livro pentaho na prática e estou começando a brincar com ele.
Estou instalando em um CentOs 6.3 minimal.
Instalação do servidor e do Java sun 1.6 ok
Instalação do data-integration ocorre erro na execução do spoon.sh

data-integration]# ./spoon.sh
/opt/data-integration
