cups was already installed.  I considered removing it, but several other
things, like ghostscript (!) are dependent on it.  I'm using
--keep-going for now.  I suspect a bug in acct-group/lp that will get
cleared up.


Why do you specify -1?  That's the most common advice I get for avoiding
slot-conflicts, but I can't imagine a system without cups.
