Vicibox Server 64bit Standard - Compilation error autoconf.h missing

I have the following setup,

Vicibox server 64 bit

I am trying to install zaptel driver for my Asterisk card.

When I try to install, it results to the following error,

make -C /lib/modules/2.6.34.10-0.6-default/build ARCH=x86_64 SUBDIRS=/usr/src/zaptel-1.4.12.1/kernel HOTPLUG_FIRMWARE=yes KBUILD_OBJ_M=“pciradio.o tor3t.o tor3e.o tor2.o torisa.o wcfxo.o wct1xxp.o wctdm.o wcte11xp.o wcusb.o zaptel.o ztd-eth.o ztd-loc.o ztdummy.o ztdynamic.o zttranscode.o wct4xxp/ wctc4xxp/ xpp/ wctdm24xxp/ wcte12xp/” modules

It says that autoconf.h missing. When I try to locate the file I saw in the path,

paranthaman-lap:/usr/src/zaptel-1.4.12.1 # locate autoconf.h
/usr/share/doc/packages/Mesa-devel/autoconf.html
/usr/src/linux-2.6.34.10-0.6-obj/x86_64/default/include/generated/autoconf.h

/usr/src/linux-2.6.34.10-0.6-obj/x86_64/xen/include/generated/autoconf.h
/usr/src/linux-2.6.34.10-0.6/include/generated/autoconf.h

I am not able to generate the autoconf.h, even I tried doing make oldconfig && make prepare in /usr/src/linu.

Any advice would help.

Gopal.
