Hi,

make buildworld fails with this error message:

mkdep -f .depend -a      /usr/src/usr.sbin/makewhatis/makewhatis.c
echo

Stop in /usr/src/usr.sbin/makewhatis.

This is the machine/cpu/arch part of my kernel configuration file:

machine         pc32
machine_arch    i386
cpu             I686_CPU
