Got a link to Achim's posts?

That is a very short ntp.conf. How does that work?
Looks like the SHM driver is not in your ntpd, otherwise you would see it
in ntpmon. So a bad ntpd build.

Why not build with all the refclocks? That is not a well tested
way to configure NTPsec.

Nothing of interest? Or Nothing? The former says the driver loaded, the
later says the driver did not load.

The build looks bad to me.
When you build ntpd, do you see a line like this?
[ 92/131] Compiling ntpd/refclock_shm.c
Does your build/config.h have these tow lines?
#define CLOCK_SHM 1 /* Enable 'Shared Memory Driver' refclock */
#define REFCLOCK 1 /* Enable refclock support */
