Arduino CLI Compiler “ino” and some basic sketches

I am trying to compile a basic Ethernet/UDP-Sketch with the cli compiler ino.

I have the newest version downloaded from their github repo.

ino init and then the content of src/sketch.ino:

#include <SPI.h>         // needed for Arduino versions later than 0018
#include <Ethernet.h>
#include <EthernetUdp.h>         // UDP library from: bjoern@cs.stanford.edu 12/30/2008

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {  
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 2, 177);

unsigned int localPort = 8888;      // local port to listen on

// buffers for receiving and sending data
char packetBuffer[UDP_TX_PACKET_MAX_SIZE]; //buffer to hold incoming packet,
char  ReplyBuffer[] = "ack";       // a string to send back

// An EthernetUDP instance to let us send and receive packets over UDP
EthernetUDP Udp;


void setup() {
     // start the Ethernet and UDP:
      Ethernet.begin(mac,ip);
      Udp.begin(localPort);

      Serial.begin(9600);

} [...]

and then ino build

lead to an error:

It seems to be the same problem as https://github.com/amperka/ino/issues/55 but they told the issue is fixed...
