Can't build wpa_supplicant [SOLVED]

[binro]

Suddenly when I emerge wpa_supplicant the compile fails with the error messages:

make: *** [../src/drivers/driver_madwifi.o] Error 1

All the missing header are in my kernel source tree but not in /usr/include. How do I make them available to wpa_supplicant?

TIA

Thanks very much, re-installing madwifi-ng-tools did the trick!
