srfo8 and wire. anything

Has anyone used a srf08 range finder with an arduino. I have found code for literally every other controller except arduino. I used the wiring library for i2c communication and found this code, (see below) but it won't compile in arduino. When I try I get a ton of syntax errors and then it says it can't determine file size. Im using the analogue ports 4,5 for the data send/receive line and the master clock, has anyone used these ports for slaving/controlling other IC's, is this info real, where am I, who said that.. ?
Any help would be great'

//- SRF08 code-------------------

#include <TwoWire.h>

void setup()
{
  Wire.begin(); // join i2c bus (address optional for master)
  Serial.begin(19200); // start serial communication at 19200bps
}
int reading = 0;
void loop()
{
  // step 1: instruct sensor to read echoes
  Wire.beginTransmission(112); // transmit to device #112 (0x70)
  // the address specified in the datasheet is 224 (0xE0)
  // but i2c adressing uses the high 7 bits so it's 112
  Wire.send(0x00); // sets register pointer to the command register (0x00)
  Wire.send(0x51); // command sensor to measure in cm (0x51)
  // use 0x52 for ping microseconds
  Wire.endTransmission(); // stop transmitting

  // step 2: wait for readings to happen
  delay(70); // datasheet suggests at least 65 milliseconds

  // step 3: instruct sensor to return a particular echo reading
  Wire.beginTransmission(112); // transmit to device #112
  Wire.send(0x02); // sets register pointer to echo #1 register (0x02)
  Wire.endTransmission(); // stop transmitting

  // step 4: request reading from sensor
  Wire.requestFrom(112, 2); // request 2 bytes from slave device #112

   // step 5: receive reading from sensor
  if(2 <= Wire.available()) // if two bytes were received
  {
   reading = Wire.receive(); // receive high byte (overwrites previous reading)
   reading = reading << 8; // shift high byte to be high 8 bits
   reading |= Wire.receive(); // receive low byte as lower 8 bits
   Serial.println(reading); // print the reading
  }

  delay(250); // wait 250ms
}
