Okay, so I discovered xcompile-ccl, which allows things to work
better since it doesn't load funky stuff as it goes along. It can't

Without l1-streams compiling, the system can't load from ppc-
boot.image in order to create the standard image. Of course, in side
the guts of this thing, I'm hopeless as far as determining what is
really wrong here... (yeah, it is interesting to glaze over the
