Ah, I see. I'm sorry, I wasn't thinking enough. Yeah, virtual/pam may be one of a list. But if nothing else, I have openssh and openssh says: RDEPEND="pam? ( virtual/pam ) No alternatives there. And I don't have virtual/pam, but do have openssh. So why does '-uDN world' not pull virtual/pam in? -rz
