Hi Bill,

This question was answered last December.  Googling for "cannot join
environment" provides the following info:

The switch from DB 4.3 to 4.4 is most likely the problem.  Berkeley DB
is complaining about incompatible file formats.  If I recall correctly,
it's complaining about log files.

The best thing to do is, using the old bogoutil, dump the wordlist to a
text file and then (using the new bogoutil create a new wordlist in a
new directory).  Then you can rename directories and be off and
running.  The process would be (roughly):

   bogoutil-old -d $OLD_DIR/wordlist.db > wordlist.txt
   mkdir $NEW_DIR
   bogoutil-new -l $NEW_DIR/wordlist.db < wordlist.txt

--- end quote ---

As you post (in your followup message), 'bf_compact' produced a working
database for you.  Since bf_compact uses bogoutil to dump the old
database and create a completly new one (and then does some directory
renaming), you now have a new database with _new_ logfile(s).
BerkeleyDB 4.4 is happy with the new logfile (since it created it).  So
you're good to go!

Regards,

David
