Forum Linux.debian/ubuntu compilation et architecture

bonjour

j'essaie de compiler la source version debian/bookworm 5.2.0-5 de libprelude a partir devuan/chimaera (debian/bullseye)
il y a 9 paquets dont un doc

j'utilise les commandes comme d'habitude:

dpkg-source -x --no-check libprelude_5.2.0-5.dsc
puis
debian/rules binary

cela bloque à la fin:

make[1] : on quitte le répertoire « /home/robertix/libprelude/libprelude-5.2.0 »
 dh_install
 dh_installdocs
 dh_ruby_fixdocs
 dh_installchangelogs
 dh_installman
 dh_python3
I: dh_python3 fs:559: renaming prelude-5.2.0-py3.9.egg-info to prelude-5.2.0.egg-info

il semble qu'il faut spécifier l'architecture demandée
pour ma part amd64 et all

dans la ligne de commande de compilation ou dans le fichier rules ?

fichier /usr/share/dh-python/dhpython/debhelper.py
ligne 214 :
arch = environ['DEB_HOST_ARCH']

voilà le fichier rules:
