What about ports? They are not allowed to install outside of PREFIX.

  $ cd multimedia/cuse4bsd-kmod
  $ make install PREFIX=/tmp/aaa PKG_DBDIR=/tmp/pkg WITH_DEBUG=
  [...]
  install -C -o root -g wheel -m 444   libcuse4bsd.a /tmp/aaa/lib
  install -s -o root -g wheel -m 444     libcuse4bsd.so.1 /tmp/aaa/lib
  install -o root -g wheel -m 444    libcuse4bsd.so.1.debug /usr/lib/debug/tmp/aaa/lib
  install: /usr/lib/debug/tmp/aaa/lib: No such file or directory
