Details:

The pkg.m script is smart enough to create the archprefix directory when it is
not present in the system (the examples below are run in a Debian GNU/Linux
system with Octave 3.6.2 installed):


$ sudo rmdir /usr/lib/i386-linux-gnu/octave/packages/
$ sudo octave --silent --no-history --no-init-file --no-window-system --eval
"pkg ('rebuild');"
warning: creating the directory /usr/lib/i386-linux-gnu/octave/packages/


This is not the case for the prefix directory:


$ sudo rmdir /usr/share/octave/packages
$ sudo octave --silent --no-history --no-init-file --no-window-system --eval
"pkg ('rebuild');"
error: could not find the file or path /usr/share/octave/packages
error: called from:
error:   /usr/share/octave/3.6.2/m/pkg/pkg.m at line 1234, column 5
error:   /usr/share/octave/3.6.2/m/pkg/pkg.m at line 418, column 16
error:   /usr/share/octave/3.6.2/m/startup/octaverc at line 26, column 1


The trivial patch attached to this bug report fixes this issue.

Note that this problem has been reported as Bug##681064
<http://bugs.debian.org/681064> against the Debian package octave.  In the
discussion around that bug report in Debian, Jordi Gutiérrez suggested that
the code has to be improved anyway ("What if creating the directory fails? Or
do we know at that point that this is a writable location?").  I think I agree
with him, but the changes need to be done to both the prefix- and the
archprefix-related code in pkg.m
