Updating sparc64 time_t, hostname not found

Am sorry to send this question which i am sure is very obvious to 
everyone else, but have now had 3 goes at updating my system to 64btt 
time_t and it always fails at the same point. I get to stage 17 on the 
instructions, only to get this error each time. have tried with the 
different flags suggested, but always the same.



cd /usr/src; /usr/obj/usr/src/make.sparc64/make -f 
/tmp/install-newk.CcO/Makefile.inc1 install
hostname: not found
"/tmp/install-newk.CcO/Makefile.inc1", line 365: warning: "hostname -s" 
returned non-zero status
===> share/info
===> include
make: don't know how to make a.out.h. Stop
*** Error code 2

Stop in /usr/src.
*** Error code 1


Anyone, please, is driving me slightly insane here, very new to freebsd 
and can't seem to work out what the problem is or how to fix it. any 
help would be much appreciated.
