Fairly easy to do using gentoo as a reference :) The ppc64 native port may have an "academic" interest, but as I wrote, I'd rather concentrate on having a biarch setup for now. > > Also make sure the compiler is biarch as the kernel build will soon > > require this. > > The compiler in the current ppc64 archive is fully biarch, i.e. it can > produce 64 bit and 32 bit binaries.
