or you can google it.

btw, why don't you use the android default build system?

you can use make kernel to build kernel.

Please check if your .config is present or not after this error ?

# vi .config

I think .config is getting deleted when you are trying to do make menuconfig..

execute the "make oldconfig" after 
"make riogrande_pepper_defconfig"
