The posters above are correct, DBD::CSV requires Text::CSV_XS which needs to be compiled. If you can compile it on a machine of the same platform, you can then upload that.

Or, you can install DBD::AnyData instead. It does not require any XS modules and has a CSV mode that behaves identically to DBD::CSV (except for 1. speed and 2. ability to handle embedded newlines). You will need to install its prerequisites - AnyData (in addition to DBD::AnyData), DBD::File and SQL::Statement, all of which are also pure perl so can just be FTP'd onto the server.
