SlimSaber help

Hey guys, so I came across this ROM a while back and I thought that someone would of compiled it by now but they haven't. So I have decided I will give it a shot. I know basic things about building Rom's but not much. I have set up my Ubuntu build environment and I'm ready to go. But I need help in the steps to make this ROM. So if anyone could help out I would really appreciate it. Thanks for reading and hope some of the top devs can help out here.

Error while building Slimsaber

All my syncs are complete built when I build it gets an error, wondering if someone could look through the code for the error.
