Win32/OLE is not going to run on your Unix system. Object Linking and Embedding (OLE) is a Microsoft technology. On the Win32 platform, you can control what Excel is doing via OLE. The same program is not possible on Unix because Excel does not run on Unix.

There are modules that can manipulate a .XLS file directly. That way it is not necessary to have Excel running. Spreadsheet::WriteExcel is one of them. There could be and probably are others.
