LinuxQuestions.org - Problems compiling kernel (gentoo on ppc)

Hello all. at the moment, i am trying to install gentoo onto an ibook (600mhz g3). however, regardless of whether i compile manually or use genkernel, i get some nasty little errors that i can't seem to find any info on. here is the latest result while attempting to compile with genkernel:
