Re: help, path, etc. not working

[Federico]

Hi, I'm having the same issue as described originally. Also on Win7 64-bit PC
using Octave-3.6.4-mingw + octaveforge pkgs. Downloaded as a 7zip from
http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.6.4%20for%20Windows%20MinGW%20installer/

Octave works well. The problem is when you want to install packages or
update packages that were not included (or have been since updated). For
example this command fails:

"pkg install parallel-2.2.0.tar.gz"

Initially the error came saying "octave 'gzip' is not recognized as an
internal or external command,operable program or batch file". However, after
Idownloaded/installed and added Gzip to the Windows Environment Variables
PATH, the error changed and it became "octave 'tar' is not recognized as an
internal or external command,operable program or batch file".

The actual error is: 
--------------------------------
octave-3.6.4.exe:4> pkg install parallel-2.2.0.tar.gz

gzip: unpack: unarchiving program exited with status: 127
'tar' is not recognized as an internal or external command,
operable program or batch file.
