It seems like the port writes directly to the target location instead of
using the destroot directory. This usually happens if the port does not
respect the DESTDIR=... argument passed to 'make install'. To test and
debug this, make sure the destroot phase can be executed locally with
trace mode enabled:

  sudo port -t destroot <portname>
