node-serialport: binding file could not be found

If i start my app including serialport var sp = require('serialport').SerialPort; i get an error from bindings that the bindings file could not be found. Is there a configuration error? It’s a fresh install.

xxx@ubuntu:~/Arbeitsfläche/node/firstapp$ node app

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
