go to your kernel source directory:
edit Makefile to read the same as the installed kernel (uname -r) (delete the word "custom" at the end of the line: EXTRAVERSION = -27.0.2.Elcustom)
run make mrproper run make oldconfig run make dep run make clean
The above sets up the kernel source so you can build and install the i2c and lm sensors drivers correctly.
cd to i2c directory under /home
run make clean run make all run make install
cd to lm sensors directory under /home
run make clean run make all run make install
do an extra depmod -a (just in case :) )
By the way, you will need to do: yum install kernel-source flex bison ... if you don't already have those packages installed. Without flex & bison, the "make all" for lm_sensors will fail, and you have to then "make clean" again before redoing the "make all."
