I will spend some time to figure out exactly how to reproduce this.

Going from recent memory (~2 weeks ago), I encountered it on my VPS box
(which does run ntpd, just FYI):

1. Initially installed with 9.1-RELEASE,
2. Upgraded to stable/9 (using svn),
3. WITHOUT_CDDL=true and WITHOUT_ZFS=true added to /etc/src.conf
4. world/kernel rebuilt/reinstalled/etc. (this includes make delete-old,
   as per instructions in src/Makefile -- which would delete
   /usr/bin/ctfconvert)
5. Fast forward many months
6. Removed WITHOUT_CDDL=true from src.conf
7. Encountered the above issue ("ctfconvert: not found") during
   buildkernel
8. Rebuilt kernel again -- same error
9. Removed WITHOUT_ZFS=true from src.conf
10. Rebuilt kernel again -- worked

This could mean WITHOUT_ZFS=true has some bearing on this situation, but
I don't see how/why, as WITHOUT_CDDL is supposed to be the "trigger" for
ctf* utilities.  I did poke around the Makefiles and framework a bit
but didn't have any epiphanies.

Like I said -- I'll try to reproduce the exact scenario.
