What steps will reproduce the problem?
1.I extracted the firmware. ./extract-firmware.sh firmware.bin
2.Made a single change in the style folder.Changed the logo.(Web GUI)
3.Rebuild it using ./build-firmware.sh.
(I also tried ./build-firmware.sh -nopad and received the same results.)

What is the expected output? What do you see instead?

Expected Output:
This is my first attempt,so I am not really sure what the exact output looks 
like. I guess it should say "Firmware appears extracted correctly!" without any 
failures or warning.

What version of the product are you using? On what operating system?
I'm using the latest version of the 
kit(https://code.google.com/p/firmware-mod-kit/downloads/list) on Ubuntu 12.04.

Please provide any additional information below.
I thought this might have happened because I tried to modify the firmware, so i 
tried rebuilding it,without making any changes,right after the extraction.
The firmware I used was ddwrt 23320 on TP Link WA901nd ver:2 router
