Apt-get :: help for Dselect in DSL

I am trying to remaster DSL. After I chroot to the hd directory, I want to use dselect to install some softwar, e.g. Mozilla or apache, which need to includ package fileutils.

When I start to install, the package fileutils can not be installed and dump errors say

fileutils tried to overwrite /bin/chgrp, but it comes from coreutils.

even I do

apt-get install fileutils

it still threw that error.

Anybody experience this case, and how to resolve it?

Thanks
