Default [ROM Build From Source Help] Error at compiling stage

Hi all,

I am in my Day 1 of ROM Developing. I have setup environment, running Ubuntu 13.10

I have this error when compiling "AOSX Rom" (AOSP modified by xperia novathor developers) the errors are in the screenshot
Was building with ssh connected to my VPS on my phone btw.
May i know the origin of this error?

Also, please link me to some noob proof guides on building roms from source as i am really really really new. I have already set up my build environment so do not link me to those threads please

TIA,
