All Over again

Im rebuilding everything with a gentoo LiveCD kernel configuration. In my 
livecd stage2
I start getting this error:

!!! catalyst: Runscript kernel build failed


Traceback (most recent call last):
 File "modules/livecd_stage2_target.py", line 324, in run_local
   self.build_kernel()
 File "modules/livecd_stage2_target.py", line 309, in build_kernel
   "Runscript kernel build failed")
 File "/usr/lib/catalyst/modules/catalyst_support.py", line 102, in cmd
   raise CatalystError,myexc
CatalystError: <unprintable instance object>
None

!!! catalyst: Runscript aborting due to error.
