cannot create chroot/etc/debian_chroot: Directory nonexistent @ ubuntu

["'2+" <electriclightheads@gmail.com>]

this is on ubuntu-maverick installed on an usb-hdd

my:

lh config -d sid -a i386 --packages "vim-nox alsa-utils dvtm htop
python python-pygame ghc6 haskell-platform c2hs libsndfile1-dev
libasound2-dev caca-utils mutt sfront csound vorbis-tools sox mpg321
yatm xine-console ecasound ghc6 live-helper mplayer rubberband-cli"
lh build

resulted into:

i took it for granted that ubuntu's live-helper could also create
debian live system
the most easy solution is
isimply installing sid to somewhere else and do the lh there?
