unable to build ntp

[Brad Gilmer]

Help please.  I am running 6.0-RELEASE, and am trying to build 
ntp.  Process fails during ./configure with the following results:

# cd /usr/src/contrib/ntp
# ./configure
--------------------------snip-------------------
configure: creating ./config.status
config.status: creating Makefile
config.status: creating ElectricFence/Makefile
config.status: error: cannot find input file: ElectricFence/Makefile.in

Interestingly, I get the same results using a 4.5 machine.  I note 
that in the /usr/src/contrib/ntp/FREBSD-upgrade file, it states in part,

For the import of NTP the following files were removed:
        ElectricFence/*

so it makes sense that ElectricFence is not there, but how do I get 
rid of the error?

Background:
I have the following entry in my crontab:
7 0-23 * * * /usr/sbin/ntpdate -s pool.ntp.org >/dev/null
In the old days, ntpdate would only send root an email if it could 
not find a server.  Now I get emails every time the cron runs, even 
though I am dumping STDOUT to /dev/null.  Problem is code in 6.0 
directs server found messages to STDERR, while 4.5 code did not 
contain this.  I want to recompile with the server found messages 
directed to STDOUT.

Thanks in advance,
Brad
