Well, I see that:

 include/ntp.h:#define REFCLK_ONCORE             30      /* Motorola UT Oncore GPS */

so this implies that your ntpd was not compiled with the ONCORE refclock.

The oncore driver compilation is system-dependent; if you go to
/usr/ports/net/ntp/work/whatever/config.h and look you should be able to 
see if it was really compiled in or not.

I would be thrilled to receive bk patches that would let folks give
an option to ntpd that would "dump" the compilation configuration.
