Error after Anaconda Customization

[Sohail Riaz <sohailinux@xxxxxxxxx>]

I customize the anaconda installer that it only install my set of
packages. But it failed during the RPM TRANSACTION STEP.

What will be the problem;

following steps i've been taken

1) edit the comps.xml 
2) did'nt create comps.rpm, if i want how i do it
3) buildinstall failed , therefore i use to edit stage2.img

Regards,
