Looks like you are deploying from Windows and you may be missing the tar
command locally or it's not in your $PATH
If you want to use Cygwin I recommend you install it using the it's Setup64 or Setup-x86 program. I believe the tar
package is one of the default packages that get installed. If not you can find it here: http://gnuwin32.sourceforge.net/packages/gtar.htm
