This is because base system implicitly assumes PREFIX=/usr/local. If
you exec `fgrep -r /usr/local /etc`, then you find '/usr/local' is
hard-coded in some files under /etc. To make poudriere build with
PREFIX=/opt, you need to create custom jail that all occurrences of
'/usr/local' in files under /etc are replaced with `/opt`. But it is
still necessary condition and not sufficiend one. Some ports may be
unable to be built with non-default prefix.
