I removed /usr/include/utmp.h and restarted inetd/telnetd/sshd.
Hopefully that does the trick..

While you're at it, I'll echo Ronald's concern-- make sure
/usr/include/utmp.h does NOT exist for you.

If it does, you must run make delete-old in /usr/src.

In the DTrace commit message thread, you mentioned that you were
upgrading from an old 8-STABLE to 9 when you got the hang.  Could you
quantify how old that 8-STABLE was/is?  If it's pre-8.3 it would be
really helpful if you could upgrade to 8.3 and test that.  If that works
then I think a note in UPDATING would be sufficient as our historical
policy has been to support upgrading to release X.Y from
(X-1).<newest>.  If it turns out that we need to upgrade to 8.4 we may
need to consider backing this out for a bit.
