Arduino IDE 1.6.2 - Error compile

Hi, I am trying to use the library in Arduino IDE v1.6.2

here is the snippet of the code

//pin definition for the SMBUS Mega 2560
#define NO_INTERRUPT 1
#define I2C_TIMEOUT 1000

#define SDA_PORT PORTD  //port definition SMBUS
#define SDA_PIN 1  //SDA PIN20
#define SCL_PORT PORTD  //port definition SMBUS
#define SCL_PIN 0   //SCL PIN21

// doco from here
// http://playground.arduino.cc/Main/SoftwareI2CLibrary

#define I2C_WRITE 0
#define I2C_READ 1

#define CHARGE 0x0d

// include the necessary libraries
#include <SoftI2CMaster.h>  //SMBUS over I2C library

byte deviceAddress = 11; // this variable represents the image to be drawn on screen

int led1Pin = 37;
int led2Pin = 36;
int led3Pin = 35;
int led4Pin = 34;
int led5Pin = 33;
int gaugebutton = 45;

int previous = LOW;
long time = 0;
long debounce = 200;

unsigned long timer; // the timer
unsigned long INTERVAL = 5000; // the repeat interval 1sec

void setup()
{
  timer = millis(); // start timer

  pinMode(led1Pin, OUTPUT);
  pinMode(led2Pin, OUTPUT);
  pinMode(led3Pin, OUTPUT);
  pinMode(led4Pin, OUTPUT);
  pinMode(led5Pin, OUTPUT);
  pinMode(gaugebutton, INPUT);

  Serial.begin(115200);  // start serial for output
  i2c_init();
//  Serial.println(i2c_init());

  scan();
}
  int fetchWord(byte func)
{
  i2c_start(deviceAddress<<1 | I2C_WRITE);
  i2c_write(func);
  i2c_rep_start(deviceAddress<<1 | I2C_READ);

  byte b1 = i2c_read(false);
  byte b2 = i2c_read(true);
  i2c_stop();
  return (int)b1|((( int)b2)<<8);
}
void scan()
{
  byte i = 0;
  for ( i= 0; i < 127; i++  )
 {
     Serial.print("Address ");Serial.print(i);
    bool ack = i2c_start(i<<1 | I2C_WRITE);  
    if ( ack )
      Serial.println("OK");
    else
      Serial.println("NO");
    i2c_stop();
  }
}

And I get these compile error messages:

complete_fuel_gauge.ino: In function 'void setup()':
complete_fuel_gauge.ino:52:12: error: 'i2c_init' was not declared in this scope
complete_fuel_gauge.ino: In function 'int fetchWord(byte)':

complete_fuel_gauge.ino:81:14: error: 'i2c_stop' was not declared in this scope
Error compiling.

It seems to me as these functions are not exposed by the library, but this is pretty much a guess.

Could you please have a look and possibly fix it up?

Thank you
