Нужен odbc dbf драйвер для linux
нашёл вот такую страничку...
авторXDB (formerly Xbase) is "a collection of specifications, programs, utilities and a C++ class library for manipulating Xbase type datafiles and indices." That is, if you deal with dBase compatible files, such as those produced by dBase, Clipper, FoxPro, etc, this might be the library for you. It supports the DBF files, dBase's NDX index files, Clipper's NTX files, DBT memo files, and possibly others.
но как я понимаю это не позваляет манипулировать dbf с помощью sql запросов...
