Which version are you using, 4.3? I built it according to your instructions
on a freshly installed lenny box (with some gcc packages from unstable). The
circular dependencies are not so nice, but it seems I got it installed. Do
you want to add amd64 packages to your repository?

m68k-linux-gnu-gcc-4.3 -v
Using built-in specs.

I get an ICE for linux 2.6.28-1
