Error when making installworld

[Ganbold]

Hi,

I did cvsup today and built world, compiled and installed kernel.
The I did mergemaster -p. But when I try to make installworld make says 
following error:

===> usr.sbin/authpf
install -s -o root -g authpf -m 6555   authpf /usr/sbin
install: authpf: Invalid argument
*** Error code 67

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

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

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

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

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

Stop in /usr/src.

What should I do? Is it some bug or am I missing something?

thanks in advance,

Ganbold
