Yes, you need to remove the conflict before you can install.

Open /var/lib/dpkg/status with leafpad/vi whatever and search for coreutils. Find the busybox section and where it says coreutils for conflicts and replaces, remove the word coreutils.

Save the file.

apt-get install libacl1 libattr1

You need to find a deb file for coreutils. I used one from maemo repo.

dpkg -i --force-all coreutils<versionetc>.deb

The bash of that website works fine.
