Thank you for your reply.
I noticed here my verbose log after my modification pkg.m.
Without it, 
octave.exe:4> pkg install -local -verbose io-1.0.3.tar.gz
cp: missing destination file
Try `cp --help' for more information.
mkdir (C:/DOCUME~1/Tatsu/LOCALS~1/Temp\oct-2)
untar (io-1.0.3.tar.gz, C:/DOCUME~1/Tatsu/LOCALS~1/Temp\oct-2)
make: Entering directory `/tmp/oct-2/io-1.0.3/src'
mkoctfile dlmread.cc
mkoctfile textread.cc
make: Leaving directory `/tmp/oct-2/io-1.0.3/src'
warning: package io is empty

The pkg stopped at preparation stage.
You said that the current pkg.m consider msys.
But for my system, it does not seem to work at all.
So I have been preparing patch for pkg.m.

What do you think about this ?

Is this the system problem ?
