Package Installation Problem

[lx]

Hello,

When I tried to install the IO package on Octave 3.6.1 on an Ubuntu 12.04 system, I got the following error message:

pkg install io-1.0.18.tar.gz
make: execvp: mkoctfile: Permission denied
make: *** [csvexplode.oct] Error 127
'make' returned the following error: make: Entering directory `/tmp/oct-e8tXVi/io/src'
mkoctfile csvexplode.cc
make: Leaving directory `/tmp/oct-e8tXVi/io/src'
error: called from `pkg>configure_make' in file /usr/share/octave/3.6.1/m/pkg/pkg.m near line 1391, column 9
error: called from:

error:   /usr/share/octave/3.6.1/m/pkg/pkg.m at line 383, column 9

How can I fix this?

Thank you,

Linda
