Yo Matthew!

I think I'm starting to realize part of the confusion here.

That statement is 100% false.  

The falsity can be readily verified.  Follow along as I do so:

I start in this directory:

/usr/local/src/NTP/ntpsec

Here is a build recipe:

./waf clean

export DESTDIR=/usr/local/
./waf configure --refclock=all --prefix=BATSHIT && ./waf build  &&./waf install

Taht does a build to here:

/usr/local/u1/local/src/NTP/ntpsec/BATSHIT/sbin/ntpd

Looking in there, no BATSHIT:

# fgrep BATSHIT /u1/local/u1/local/src/NTP/ntpsec/BATSHIT -r
# 

Oddly, the install SAYS it installed everything, but only modeuls got
installed on my system.

The modules installed here (not exactly sure why, problem for another day):

/usr/local/usr/lib64/python2.7/site-packages/

When  I look, no BATSHIT:

# fgrep BATSHIT /usr/local/usr/ -r
#

So, 100% proven, --prefix does NOT go into ANTYHING that gets installed.

--prefix and DESTDIR, are ONLY used to decide where to install.  And as
the above shows, how they work together not exactly obvious.
