make installworld fails

[Valentin Bud]

elo list,

just updated a newly installed freebsd 7.1 system and it crashed here:

===> rescue (install)
===> rescue/librescue (install)
===> rescue/rescue (install)
install -s -o root -g wheel -m 555   rescue /rescue
install: rescue: No such file or directory
*** Error code 71

Stop in /usr/src/rescue/rescue.

I have updated the sources using the csup method then
# make buildkernel  KERNCONF=CUSTOMISED
# make installkernel KERNCONF=CUSTOMISED
# mergemaster -p
reboot
#make installworld

# uname -a
