There is a reference implementation of nptd available from ntp.org! 
Open ntpd is a different (and competing) product which is not supported 
here.  The reference implementation from ntp.org requires that you have 
a C compiler (gcc will do the job).

If you have gcc (and gmake) installed, you can do:
wait for a while and you're done.  You may need to move the ntpd 
executable to wherever your O/S keeps executables (/bin, /usr/bin, /opt, 
. . . .)

There is a lot of documentation, advice, etc, available at ntp.org.
