Both suggest that opening a database file failed.  Somewhere you have a
database file, right?  Suppose it's named hammie.db.  Try this:

    % python
    Python 2.4a0 (#5, Nov 23 2003, 20:09:38) 
    [GCC 3.3 20030304 (Apple Computer, Inc. build 1493)] on darwin
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import shelve
    >>> db = shelve.open("hammie.db")
    >>> len(db)
    40569
    >>> db.close()

Does that succeed for Python 2.2 but fail for 2.3?  If so, I'd suspect a
file version change.  If not, continue on to step two.

    % python
    Python 2.4a0 (#5, Nov 23 2003, 20:09:38) 
    [GCC 3.3 20030304 (Apple Computer, Inc. build 1493)] on darwin

    >>> from spambayes.storage import open_storage
    >>> s = open_storage("hammie.db")
    >>> s
    <spambayes.storage.DBDictClassifier instance at 0x764968>
    >>> dir(s)
    ['WordInfoClass', '__doc__', '__getstate__', '__init__', '__module__', '__setstate__', '_add_msg', '_getclues', '_post_training', '_remove_msg', '_wordinfodel', '_wordinfoget', '_wordinfokeys', '_wordinfoset', '_write_state_key', 'changed_words', 'chi2_spamprob', 'close', 'db', 'db_name', 'dbm', 'learn', 'load', 'mode', 'nham', 'nspam', 'probability', 'probcache', 'spamprob', 'statekey', 'store', 'unlearn', 'wordinfo']
    >>> s._wordinfoget("python")
    WordInfo(2, 14)

Does this succeed for one version of Python but not the other?

I suspect you have some sort of version-related problems, but they are
related to the FreeBSD environment, not directly to Python's versioning.
