[htdig] Problem with db2

[Per o. L. <pe...@in...>]

After upgrading from 3.1.6 to 3.2.0-b6 I can rundig and htfuzzy without 
errors, but a search produces the following result (from the Apache log):

DB2 problem...: /usr/local/share/htdig/common/word2root.db: unsupported 
btree version number 7
DB2 problem...: /usr/local/share/htdig/intersonic/db.words.db: 
unsupported btree version number 7
DB2 problem...: /usr/local/share/htdig/intersonic/db.words.db: 
unsupported btree version number 7

OS is  FreeBSD 4.9-RELEASE-p4
All the old databases were deleted before run.

All help welcome!

Thanks,
