OSX - problema installazione WxWidget

ciao
per il secondo semestre dobbiamo fare una simulazione grafica in c++ e utilizzeremo wxwidget e opengl.
Il mio sistema è MacOSX 10.6. Per installare wxwidget ho scaricato una cartella da wxwidgets.org/downloads/ e ho seguito le istruzioni che cerano nel file install-mac.txt. All'inizio non compilava perchè c'era un problema con l architettura 64bit ma poi ho trovato la soluzione sul sito e sono riuscito a compilare e terminare l installazione. Ho provato a compilare uno degli esempi che danno loro (samples) e funziona, però se cerco di compilare qualcosa di mio non funziona. Mi restituisce questo:
