The kernel mkfiles don't know how to build dependencies from the cmd tree. The mk you're doing knows fossil is missing or out of date, but not how to do anything about it. Build it yourself. I mk all of /sys/src/cmd to be safe, but you could just hit the list you need for your kernel (whatever files you're building in).
The 'pc' configuration doesn't have this problem because it doesn't include fossil (and a few other things pcf has). See the 'bootdir' section of the config file. Anthony
