wl.ko

Hello,

To have my wifi avaiable on my HP Pavillon tx1420 AMD Turion64, I'm
trying to compile wl.ko following the instructions on
http://www.broadcom.com/support/802.11/linux_sta.ph

however:
root@wheezy:~/hybrid_wl# make clean 
KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd` clean 
make[1]: Entrando no diretório `/usr/src/linux-headers-2.6.39-2-amd64'
