Sounds like it didn't compile the cuw_pc kernel.. If you run builds back 
to back with different kernels, the build scripts don't know that it 
shouldn't skip the kernel step.  If you start at the kernel or kernelenv 
step, I think it should work.  Also, the missing kernel isn't fatal so the 
creation of the iso will still happen, it just won't boot.

I tweaked a few build files at some point to prevent this from happening; 
if you want you can try the attached patch and see how it works for you.
