That sounds quite old and I would not consider 0.6.9 to be supported
anymore, so probably not much point in trying to debug that version.

How about listing some of the errors so that someone could help with
this? Most likely you do not have libnl development packages installed
or need to add CONFIG_LIBNL20=y or CONFIG_LIBNL32=y to hostapd/.config
depending on which version of libnl you are using.
