As a PS:

Looking at the log I create with ntpq, which runs when I start it with a 
30 minute interval, I note that although it appears to be working, the 
"offset" value is slowly incrementing in the negative, so apparently it 
needs built with more options than just --enable-clockctl.  IOW its not 
working even though I installed it while sudo'd.

Looking into it.

Cheers, Gene Heskett
