I just pushed a patch that should fix this. Part of the problem is that the --no-dph flag to sync-all doesn't disable the primitive & vector repos like it used to, because they are now submodules. I've fixed it in the build system instead.

Yeah, your change fixed 'make' for stage1only. make install does not work though (and didn't before): $ make install DESTDIR=/var/tmp/portage/cross-ia64-unknown-linux-gnu/ghc-9999/image/ ...
