converter dbf para mysql

Olá amigos, estou precisando de ajuda para interpretar um script que converte de dbf para mysql:

no meu caso ele está gerando somente o cabecalho e dá o erro nesta fução: if (!function_exists('dbase_open'))

{

 die("DBF support (--enable-dbase) is not enabled");

}

ele retorna : DBF support (--enable-dbase) is not enabled

para executar o script, deve entrar no prompt e digitar:

php dbf2sql.php <dbfile> <tablename> > output.sql

encontra disponivel em: http://www.pablo.blog.br/63

dbf2sql.php

<?
if (count($argv) != 3)
