Error with the i2c master library for MLX90614

Hey! i'm having problems with the use of the i2c master library for the use of the MLX90614
with the code of this page:
http://bildr.org/2011/02/mlx90614-arduino/
but when i compile the example i get this message:

In file included from MLX90614.ino:1:
/Users/johannstark/Documents/Arduino/libraries/I2Cmaster/i2cmaster.h:88: fatal error: io.h: No such file or directory
compilation terminated.

please i need help with this smiley-cry
thanks

The error message describes the problem: the “i2cmaster.h” is missing.

You have a #include <i2cmaster.h> statement in your sketch that wants to read in this file and can’t find it.
Here it is:

@brief I2C (TWI) Master Software Library

Basic routines for communicating with I2C slave devices. This single master 
implementation is limited to one bus master on the I2C bus. 

This I2c library is implemented as a compact assembler software implementation of the I2C protocol 
which runs on any AVR (i2cmaster.S) and as a TWI hardware interface for all AVR with built-in TWI hardware (twimaster.c).
Since the API for these two implementations is exactly the same, an application can be linked either against the
software I2C implementation or the hardware I2C implementation.

Use 4.7k pull-up resistor on the SDA and SCL pin.

Adapt the SCL and SDA port and pin definitions and eventually the delay routine in the module 
i2cmaster.S to your target when using the software I2C implementation ! 

Adjust the CPU clock frequence F_CPU in twimaster.c or in the Makfile when using the TWI hardware implementaion.

@note 
  The module i2cmaster.S is based on the Atmel Application Note AVR300, corrected and adapted 
  to GNU assembler and AVR-GCC C call interface.
  Replaced the incorrect quarter period delays found in AVR300 with 
  half period delays.

@par API Usage Example
 The following code shows typical usage of this library, see example test_i2cmaster.c

@code

#include <i2cmaster.h>


#define Dev24C02 0xA2   // device address of EEPROM 24C02, see datasheet

int main(void)
{
  unsigned char ret;

  i2c_init();               // initialize I2C library

  // write 0x75 to EEPROM address 5 (Byte Write) 
  i2c_start_wait(Dev24C02+I2C_WRITE);   // set device address and write mode
  i2c_write(0x05);            // write address = 5
  i2c_write(0x75);            // write value 0x75 to EEPROM
  i2c_stop();               // set stop conditon = release bus


  // read previously written value back from EEPROM address 5 
  i2c_start_wait(Dev24C02+I2C_WRITE);   // set device address and write mode

  i2c_write(0x05);            // write address = 5
  i2c_rep_start(Dev24C02+I2C_READ);    // set device address and read mode

  ret = i2c_readNak();          // read one byte from EEPROM
  i2c_stop();

  for(;;);
}

Copy and paste this code and save it as i2cmaster.h in your directory

I am using the orignal i2c-lib which works fine with all devices on the bus
