HostAP Digest, Vol 124, Issue 32

Thanks Mihai. As there is no libnl2 or libnl3 package for Ubuntu
Lucid, I downloaded source for libnl 3.2.22 and built and installed it
without apparent incident using
http://www.linuxfromscratch.org/blfs/view/svn/basicnet/libnl.html.

Unfortunately I still get similar looking compile errors with
../src/drivers/driver_nl80211.c when trying the hostapd 2.0 install
once more (make clean, make all).
