La gestion d'un hôte FreeBSD avec Ansible échoue : Objet partagé "libdl.so.1" non trouvé, requis par "Python". \r\n

Gestion de FreeBSD sur Raspberry pi 3 (FreeBSD-aarch64-12.0-GENERIC-320146M du projet RaspBSD - http://www.raspbsd.org/ ) échoue.

L'hôte de contrôle est MacOS 10.13.2.

Python est installé avec succès sur l'hôte géré ( rpi3_freebsd ):

$ ansible -m raw -a "sudo pkg install -y python27" --user drew --ask-pass rpi3_freebsd

Cependant, lorsque j'essaie d'exécuter un playbook, ansible renvoie l'erreur suivante :

La seule dépendance pour ansible est Python qui est satisfait.

Quel est le problème et comment puis-je le résoudre ?

Merci.
