I know your problem. Following is a script file that does
the job of installing the controls toolbox in the appropriate
locations. You can use the same script for applying updates
of the controls toolbox. Decompress the files anywhere
and invoke the script with

   ./install-ocst all

It will ask before doing anything.

==========================================================================
  install-ocst attempts to install (or update) the OCST (Octave controls
  toolbox) of your version of Octave.

   The files in the subdirectories "general", "linear-algebra",
   "strings", "plot", and "control" will be copied to the Octave data
   directories with proper permissions.

   The install and update procedures differ in the way they perform the
   copy of the  files in this OCST version.

   o all     Copy all files to the Octave data directories assuming that
             this version is newer. Install does not ask any questions.
             This modfe is best if you are the system administrator you
             just want to install the control stuff.

   o select  Copy all files but ask before replacing an existing file
             which differs from the one in this distribution. The update
             mode is appropriate for developers. New files will be
             copied without confirmation.
             Note: it can be very annoying to confirm the replacements.
