Right, but with rosetta, you *should* (I haven't tried it) be able to  
setup a ppc chroot and within that chroot it'll look and feel like ppc  
as far as your build train is concerned (thus it's not "cross"  
compiling specifically).  But still, the lack of ppc64 support within  
rosetta is probably the bigger issue (atleast in my mind)
