problem with isomaker (maybe)

Hi all,
I'm trying to morph a morphix CD. I've took two config files
from /usr/share/mmaker/templates

mkdir morphing
cd morphing
cp /usr/share/mmaker/templates/basemod-2.6.13.xml basemod.xml
cp /usr/share/mmaker/templates/lightgui.xml lightgui.xml

then I edited  basemod.xml to change the source of knoppix deb
packages (the one in the file did not seem to work) so that now it reads

  <repositorylist>
   <repository type="debian">ftp://ftp.debian.org/debian</repository>
<!--   <repository type="debian">ftp://127.0.0.1/debian</repository>-->
   <repository type="plain">http://www.morphix.org/debian</repository>
<repository
type="plain">http://debian-knoppix.alioth.debian.org</repository>
</repositorylist>

and finally I used

isomaker -b basemod-2.6.13-my.xml -m lightgui.xml \
-r http://www.morphix.org/debian/udeb -p grub-gfxboot-iso-udeb \
-p morphix-cdrom-misc-udeb -p morphix-grub-menulist-udeb \
-p morphix-iso-grubtheme mylivecd.iso

to obtain the iso. When I tested it with

qemu -cdrom mylivecd.iso 

I've got an error:

...
losetup: /dev/cloop: no such device or address
Can't find MORPHIX filesystem, sorry
...

Can someone help, please? 

Notice two things:

1) qemu is properly configurated; indeed I'm able to run the original
morphix iso images

2) I'm doing everything from inside a chroot in the main module of a
MorphixCombined-LightGUI-0.5-pre4.iso

Best,
	G.
