Problèmes de la bibliothèque Gnupg sur Solaris 11

J'ai installé gnupg à partir du dépôt officiel de Solaris 11, mais je rencontre des problèmes de bibliothèque. Voici l'erreur que je reçois :

ld.so.1: gpg2: fatal: relocation error: file /usr/lib/libreadline.so.5: symbol tgetent: referenced symbol not found
