Configure options for setting directories not working for me

So I am building RT with the following configure options.

When i do a ‘make install DESTDIR=/tmp/rt’ The only root folder is /usr and
everything is inside of that.
I would think that i should have /usr, /etc,/var and /srv showing up as root
directories. Maybe i am misinterpreting the documentation? IE:
"–sysconfdir=DIR read-only single-machine data [PREFIX/etc]". The
[PREFIX/etc], does that mean no mater what i set as the “sysconfdir” that it
will always go in what’s defined as the prefix?

The other question i have is about all the HTML files under the share dir.
If i wanted to put them in the actual webdir, is what i have defined the
correct way to do that(–datadir=/srv/www/htdocs/rt )?
