    The btree format allows arbitrary key/value pairs to be stored in a
    sorted, balanced binary tree.

    As with the DB_HASH format, it is possible to provide a user defined
    Perl routine to perform the comparison of keys. By default, though, the
    keys are stored in lexical order.

Evidently, if one does not ask for a "sorted, balanced binary tree", one
gets an "unsorted, unbalanced, binary behemoth", though perhaps only on the
Mac.

Since DB_FILE is recommended in the Perl Cookbook (p. 492), I'd assume it's
platform independent (apart from certain performance characteristics which
you seem to have encountered).
