Ma question est comment installer ce logiciel? Oui j'aurais pu passer par les dépots mais j'ai installé Debian lenny et mon fichier /etc/apt/sources.list est en stable. Donc la version de network-manager est la 0.6.6 et celle que j'ai télécharger est la 0.7.1

Avec le fichier README et INSTALL j'ai pas trop compris donc je fais appel à vous...
Merci d'avance pour votre aide...
