When I try compiling the example for the LCD4Bit_mod in arduino 1.0.2, it says:

Is this code incompatible or is there any additional libraries to be added. File was downloaded from:

You need #include "WProgram.h" if i am not mistaken

use "Arduino 1.0 Compatible Library (Thanks to Glendon Klassen)" source code in the product page.
