Je n'arrive pas à utiliser Xerces 3.0.1

J'essaie de compiler le code donné en exemple suivant :

J'ai essayé avec les source, en les compilant, avec les binaires. Rien.
Pour l'instant j'ai donc l'archive xerces-c-3.0.1-x86-linux-gcc-3.4
et le répertoire correspondant.
Je suis la procédure pour les export :

Je lance la compilation dans le même terminal :
