I don't know whether this will help but I've found that some firmware won't compile with the later Arduino software, I don't know why it is but whenever I have come across compiling errors I just compile in Arduino 0023 or 0022 and it works fine. It's something I've been meaning too post a question about.
Cheers

Hi Guys, To make the LCD work you have to uncomment #define ULTRA_LCD and you have to add the LIBRARIES to the marlin folder, then compile and then upload to the arduino. Each manufacturer got his own libraries for his lcd.
