Probleme pour installer gammu

Bonjour,

Je cherche à envoyer et recevoir des SMS depuis mon Mac et on m'a recommander d'utiliser pour ça le module Gammu de Python. Je l'ai donc téléchargé et installé par ligne de commande en suivant ce tutoriel :
https://back2arie.wordpress.com/2010/07/16/installing-gammu-on-mac-os-x/

Mais après avoir tout fait (à priori comme il faut), impossible d'utiliser Gammu :
- si je fait un import gammu dans l'IDLE de Python, il me retourne "No module named gammu"
- si j'essaie d'exécuter "gammu --identify" depuis le Terminal, il me dit "Command not found".

J'en conclu que Gammu n'est donc pas installé ?

En parcourant les lignes qui s'affichent dans le Terminal pendant la configuration et le "make" de gammu, je repère les warnings suivants :

./configure :

Le problème viendrait-il de là ?
Merci d'avance pour votre aide, car j'ai vraiment besoin de ce fichu gammu.
