Thanks.


pkg prefix /home/tatsuro/work/octave/octave-forge/4.0.3 
/home/tatsuro/work/octave/octave-forge/4.0.3
pkg local_list ~/.octave_packages
more off
cd /home/tatsuro/work/octave/gsl/gsl-hg/target
pkg install -verbose gsl-1.1.0.tar.gz

In the last of pkg install

error: couldn't append to 
save: unable to open output file ''
error: called from 'install' in file 
/opt/octave/4.0.3/share/octave/4.0.3/m/pkg/private/install.m near line 289, 
column 7



Perhaps setting
pkg local_list ~/.octave_packages

is inadequate.
