public class ReplacementBuildPostprocessor : MonoBehaviour
{

    public static void OnPostprocessBuild(BuildTarget target, string pathToBuild)
    {
        UnityEngine.Debug.Log("Beginning postprocess: "+pathToBuild);

        string player = target.ToString() == "iOS" ? "iPhone" : target.ToString();
        string arguments = String.Format("{0} {1} {2} {3} {4} {5} {6}", pathToBuild,
            player, "", PlayerSettings.companyName, PlayerSettings.productName,
            PlayerSettings.defaultScreenWidth, PlayerSettings.defaultScreenHeight);

        UnityEngine.Debug.Log("Starting script: perl " + Application.dataPath + "/Editor/PostprocessBuildPlayer" + " " + arguments);

        Process process = new Process();
        process.StartInfo.FileName = "perl";
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.Arguments = Application.dataPath + "/Editor/PostprocessBuildPlayer" + " " + arguments;
        process.Start();

        // Synchronously read the standard output of the spawned process.
        StreamReader reader = process.StandardOutput;
        string output = reader.ReadToEnd();

        // Write the redirected output to this application's window.
        Console.WriteLine(output);

        process.WaitForExit();
        process.Close();
    }
}

Fantastic. Might not matter, but the file from my legacy project was named PostProcessBuildPlayer (title case).
