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.
