Something else must be going on. This is the code from configure.ac that 
checks for libnl-3:

         if test "x$ac_cv_header_netlink_netlink_h" = xyes; then
             AC_EGREP_HEADER([nl_socket_free], [netlink/socket.h],
                             [AC_DEFINE([HAVE_LIBNL3], [1],
                             [Define to 1 if <netlink/netlink.h> 
provides the
                             libnl3 API])])
         fi

Thanks,

Bart.
