Hrm.  We need to do something so that you don't get stock-looking version 
numbers from not stock source.

1.2.7 as shipped does not generate the 'D' tag.

If you apply the following patch to what you're running on the target 
server, it will ignore the 'D' tag and its 16-bit value.  This should allow 
you to restore the dump file (the vos restore I suggested earlier should 
work) or to move volumes to that server.  However, whatever data was 
supposed to be represented by the 'D' flag will be lost in the process.

It might do to wait a day or two and see if anyone else knows what this tag 
is, and/or ask around locally.  I've never heard of it, but it may be some 
private modification.
