DB_File is usually implemented on top of whatever the latest Berkeley
DB is available. The file formats are usually not compatible from
major version to another major version. I believe RH 6.2 uses bdb v2
and Suse uses a newer version 3 or 3.1. Use the rpm -q -a command to
find out which versions are which.
Anyway, you need to try out the db_upgrade command, it should upgrade
the db file to the latest format. It might not be installed by
default, so check your local docs. (I think it's in db3-utils, or
some such..)
You might also try out the BerkeleyDB module for access to more
interesting features provided by the later versions of this library.
In particular the transactions subsystem is very, very cool.
Good Luck
