It is much easier when a file is actually missing so that was my first 

What is probably happening is that when it tries to compile:


that something is missing from one of the includes.  That is, the 
object: "iw_pr_ether" should be defined in one of the included header 
files and it isn't.  My standard method is to Google for the name of the 
missing object.

I think that this is in: iwlib.h.

Do you have some 'wireless' package installed?  Do you need it?
