cant export db

[srbob]

Hi everybody

I'm getting this when I try to export my database, I googled but I didnt get anything related to...

Fatal error: require_once(): Failed opening required 'Spreadsheet/Excel/Writer.php' (include_path='.:/opt/lampp/lib/php') in /opt/lampp/phpmyadmin/libraries/export/xls.php on line 5

I've been looking unsuccesfully for the 'Spreadsheet/Excel/Writer.php' file...

Any idea?
