libpq.so.5: impossible d’ouvrir le fichier object partagé: aucun fichier ou répertoire de ce type – /gds/apps/ruby-1.9.2-p180/lib/ruby/gems/1.9.1/gems/pg-0.14.1/lib /pg_ext.so

J’essaie de lancer un script (script ruby) sur un serveur Linux. J’ai l’erreur ci-dessous: je ne suis pas sûr de la nature du problème, mais cela ressemble à un problème de bibliothèque partagée. Experts Linux, pouvez-vous s’il vous plaît éclairer ce que le problème pourrait être?
