est ce que python2.4 est toujours installés en concurrence avec la 2.5?

faudrait peut-être voir du côté de la var PYTHONPATH le ptit programme ptyhon-config et sinon le lien symbolique "python" vers quoi il pointe.
Tu peus poster l'ebuild aussi? histoire de voir cmt il a installé la 2.5?

python 2.4 est toujours la

python-updater ne marche plus comme portage (probleme d'importation de modules qui existe plus (entres autres))

je peux virer l ancien ficheir /usr/bin/python sans problemes ????

Merci !
