I did make S=../src package the first time, but then for some reason i 
was trying without defining the S variable.
Making it properly this time i went further, but still the build failed 
in if_rum with error if_rum.c:1118 too few arguments to function 
'ieee80211_input' and several warnings about nested extern declarations 
and implicit declarations of the ieee80211 functions.
I'll try disconnecting if_rum from the build to see if will help.

Thanks for your help!
