I have a data file created with perl containing 4 databases, 3 has and
1 btree. When I try to dump any of the 4 databases I receive the
following:

db_dump: unable to join the environment
db_dump: dns.dat: unsupported btree version: 9
db_dump: open: dns.dat: Invalid argument

Has anyone experienced this before and come up with a solution/fix?

Was db_dump built with the same version of Berkeley DB as the Perl module
you are using?
