[#2475] Revert "[#858] altered unpack behavior"

Reverting this commit due to the 'stat' behavior on MacOSX
(BSD) not having a '-c' option.  There may be a better way
to do this, but for now, we need the cross-platform
functionality of the FakeTarget.

This reverts commit 48eaf6791440eae8f6e34963a3604784b7ff327c.
