I built it myself as per:
https://www.ntpsec.org/white-papers/stratum-1-microserver-howto/
No particular problems noted during the installation.

ntpd --help says (at the end):
This version was compiled with the following clock drivers:
         NMEA         PPS         SHM        GPSD

Found the error in syslog:
Jun 25 22:45:18 chronos ntpd[18167]: CONFIG: readconfig: parsing file: 
/etc/ntp.conf
Jun 25 22:45:18 chronos ntpd[18167]: CONFIG: Unknown driver name local

So, I built ntpd without a local refclock ?   I used clockmaker and I 
don't recall any driver options.   Perhaps I could rebuild, with some 
waf config option.
