[ntp:questions] new 4.2.8 build on older buntu

Greetings all;

1. Several of these questions below really ought to be in the not built 
man pages, or in the tarballs html files, but are not.

2. Where does it expect to find its ntp.conf file?  On old buntu, its 
/etc/default/ntp where ntp is the file.  This is the location and filename 
used in the /etc/init.d/ntp control script.

3. I first built it with --enable-clockctl, but this is failing and the 
ntpq responses are showing a steady negative drift.

So next I tried configureing it with a few more of the usual suspects 
./configure --enable-clockctl --enable-linuxcaps --enable-accurate-adjtime

But the make then bails out:

ntpd.c:108:29: error: sys/capability.h: No such file or directory
ntpd.c: In function ‘ntpdmain’:
ntpd.c:970: error: ‘cap_t’ undeclared (first use in this function)
ntpd.c:970: error: (Each undeclared identifier is reported only once
ntpd.c:970: error: for each function it appears in.)
ntpd.c:970: error: expected ‘;’ before ‘caps’
ntpd.c:976: error: ‘caps’ undeclared (first use in this function)

make[1]: *** [all-recursive] Error 1

This file exists in several locations, the most obvious being:

This looks to be a correctable by a configuration argument, but which one?

Thanks everybody.
