I am saying that the ntpd that ships with Ubuntu 14.04 is limited because
it was built on a system where timepps.h was not present, and thus the
ATOM and JUPITER (and a couple other) refclocks were not included in the
binary.  Even though PPS support is present in the kernel.

I built ntpd locally after installing the package pps-tools, which
includes timepps.h, and then everything is OK.
./configure detects the presence of timepps.h and then enables all
refclocks with PPS support.

But I would prefer not having to build ntpd to get the ATOM refclock
working.
