Script Compiler error?

Compiler error when i build for IOS runs fine in editor. and it is this script that is causing the error.

using UnityEngine;
using System.Collections;
[RequireComponent (typeof(AudioSource))]
public class splashpager : MonoBehaviour {
public MovieTexture movie;

    void OnGUI()
        GUI.DrawTexture(new Rect(0, 0, Screen.width, Screen.height), movie);
	void Start () 
	audio.clip = movie.audioClip;

Movie Texture isn’t supported on IOS and Android. But at the bottom of this doc page there is info on playing movie clips on IOS:
