sounds like you have it set to lzma compress but don't have any lzma tools installed. You can either install app-arch/lzma-utils or change the compression. (I don't use genkernel so I'm not sure as to how on that one, maybe someone else can fill you in on that)

you have to install lzma tools in order to work with bzImage. Install it with emerge lzma-utils

in the chroot, you can:
Code:
emerge lzma-utils

or
Code:
emerge xz-utils

or
Code:
genkernel --menuconfig all

in menuconfig set
