So I tried this(using --portage -b instead) and I don't quite get it to work.
My binpkg foo is pretty much non existing :)

So far I get a bin pkg in
/usr/portage/packages/cross/powerpc-4.4.4_softfloat-linux-gnu/cross-powerpc-4.4.4_softfloat-linux-gnu
and to get at it I must change PKGDIR to /usr/portage/packages/cross/powerpc-4.4.4_softfloat-linux-gnu/
get at the package. Does it have to be there or could it be moved to /usr/portage/packages/
so emerge finds it without messing with PKGDIR?

Next problem, how do I force other computers to use the bin pkg? Unless one
passes -G to emerge, emerge rebuilds the pkg and I don't want that
as I have passed EXTRA_ECONF args and added a small patch to glibc as well.
