Hope that anyone can help me

I am builiding the examples.
And for some examples it says says that it can not find
gui.xml file

Could not open file: /home/nico/clanlib-doc/examples/CTalk/../../Resources/GUIStyleSilver/gui.xml

that is correct because there is no such directory Resources with gui.xml.
Can any one tell me wher i can find this file, of must i made it myself and if so wath sould this file contain.

Many regards
Nico Heiligers
