Did you use the -u switch on your dump command. It looks like
you must have if dumpdates is written OK. I haven't tried this
and, if lacking a -u isn't the problem, unfortunately I do not have
an answer to your main question.
But, I wonder why you chose level 9 for your change dumps. It sort
of defeats the system. It would be more normal to use level 1.
I know that [some much] earlier versions of BSD dump only took levels
up to 5, but I presume that since they include up to 9 in the documentation
it should work.
