pump.io et Toutatis

Bonjour,
Puisque Identi.ca a fermé l'enregistrement de nouveaux comptes utilisateurs en mars dernier, j'ai essayé d'installer pump.io sur mon toutatis mais je n'y arrive pas et j'ai absolument besoin d'avoir accès à irc.freenode.org pour suivre les évènements du Libre cet été et les activités de divers associations et dans le terminal, j'ai:

:~$ sudo npm install -g pump.io
