Topic: Solidoodle 4 LCD upgrade, Mainboard REV E

Currently have a SD4 and I want to add an LCD/SD control board to it, I have soldered pins to EXP1 on the board, but I am stumped by the firmware changes. Whenever I try to compile it I get the following error:   
 
Marlin_main.cpp: In function 'void process_commands()':
Marlin_main.cpp:881: error: 'BLEN_C' was not declared in this scope
Marlin_main.cpp:887: error: 'BLEN_C' was not declared in this scope


I would like to keep this board if possible, but I can't figure out what the issue is (maybe pin assignments?). A also found a modified version of the firmware for SD2/3's, but it seems to rely on an ATMEGA 1286, while my REV E has a AT90USB1286. I was able to compile this version for an ATMEGA 1286, but changing the board causes it to not compile. Here is the modified firmware:
