iOS - Errore sqlite3 in un applicazione che usa le API di Facebook

Ciao a tutti, sto sviluppando un'applicazione per un mio amico e per farlo ho bisogno delle librerie che mette a disposizione Fb. Ho seguito la guida che c'è sul sito passo per passo ma durante la compilazione mi appare uno strano errore, anzi 14:

Sapete come posso risolvere questo problema?

mi dà tanto l'idea che sul pc non trova le librerie per sqlite3 ma non usando il mac non so aiutarti di più...
