kernel 2.6.13.1 make: *** [deb-pkg] Error 2

["David A." <achoice@gmail.com>]

Hi,

I've downloaded 2.6.13.1 kernel, successfully run "make all".
But when I run "sudo make deb-pgk" i get;

...
 INSTALL net/ipv4/netfilter/iptable_nat.ko
  INSTALL sound/core/snd-rtctimer.ko
if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F

Any ideas?
