Euh, ya pas de raison qu'ils enlèvent le support PDO de 5.2 à 5.3. Et puis tu crois qu'ils vont intégrer des pilotes PDO sans intégrer PDO ? Un peu de logique voyons.

Le problème doit venir de ton code, rien d'autre. Donc poste le.

O o jamais vu ca de ma vie chez moi on fait CFLAGS="-O2" mais enfin bref,

--enable-pdo=shared \ sert à rien il n'y a que les options propre à chaque moteur de base de donnée qui servent, en fait la plupart de tes options de configure sont fausses, as tu fait ./configure --help pour les sélectionner?

./conf_install: line 14: --with-pdo-pgsql=shared: command not found
