Hello Jim,
Yes, doing "cvs -z3 co -r oacs-4-6 -d oacs-dotlrn -N acs-core" checks out fine but everything is stores as you say, "oacs-dotlrn/openacs-4" so ... I don't know if this is a problem in the CVS repository but still, the easiest solution is just to avoid using "-d" and then to rename the "openacs-4" directory to whatever we want it to be called.
Thanks!
