What version of Berkeley DB are you using?  Try this command:

    rpm -qa | egrep '^(lib)?db'

It might report something like

    db1-devel-1.85-6mdk
    libdb3.2-devel-3.2.9-2mdk
    db1-1.85-6mdk
    libdbtcl3.2-3.2.9-2mdk
    db2-2.4.14-3mdk
    libdb3.2-3.2.9-2mdk

Note that I don't have anything like "libdb3.2-utils-3.2.9-2mdk".  If you
don't but have your Mandrake CD around, install that RPM.  That will give
you a bunch of commands which begin with "db_".  Try running db_recover on
your corrupt database file and see if it fixes the problem.

What does ldd say about the version of libdb linked into your bsddb.so file?
Try something like this:

    % ldd /usr/local/lib/python2.2/lib-dynload/bsddb.so 
            libdb-3.2.so => /lib/libdb-3.2.so (0x4001c000)
            libc.so.6 => /lib/libc.so.6 (0x400a3000)
            /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

You want the -utils RPM which corresponds to the libdb version bsddb.so was
linked against.  On Mandrake systems you can install multiple versions of
libdb simultaneously.
