make installworld failure

I have been running  into this problem for a few weeks now, when i get 
to make installworld it will:
 >>> Installing everything..
--------------------------------------------------------------
cd /usr/src; /usr/obj/usr/src/make.i386/make -f Makefile.inc1 install
===> share/info
===> include
creating osreldate.h from newvers.sh
touch: not found

Has anyone seen this or know mto fix this? The way i do upgrades goes 
like this:
cd /usr/src
make buildworld
make buildkernel KERNCONF=GENERIC
make installkernel KERNCONF=GENERIC
reboot
cd /usr/src
mergemaster -p
make installworld
