Missing file from GreenJ

[racarpenter]

I am attempting to compile GreenJ and I am getting this error after I run make:

make: *** No rule to make target ../res/images/greenj.icns', needed by../bin/mac/GreenJ.app/Contents/Resources/greenj.icns'. Stop.

This file is nowhere to be found and I do not know why it is asking me for this/why I need this file. Any help would be appreciated! Thank you.
