Compiling hostapd from git with libnl also from git...

Thanks for your reply. I was just checking and your are correct, I
fixed my makefile since I had changed it to link to the libnl-genl
libary. I've removed all of my changes I did to fix the various symbol
resolution errors I was getting. I'm now just using the hostapd 0.6.6
and the libnl delivered with my distro. It compiles fine and runs.
Unfortunately I'm having the same problems with my access point. It is
not being advertised and the debug out that I've listed on this site
shows that the TX callback is failing:
1228840205.186928: handle_tx_callback(): MGMT (TX callback) fail
1228840205.186954: mgmt::proberesp cb
I modified the debug to include the name of the function where the
failure was being reported.
