In 2.9.6, you should also have some lines like this:

  autoload ("__gnuplot_plot__", fullfile (fileparts (mfilename ("fullpath")), 
  autoload ("__gnuplot_replot__", fullfile (fileparts (mfilename ("fullpath")), 

in the PKG_ADD file that is in the directory with the .oct files.

Sorry that this is not well-documented, but you are using a
development version...

If you don't have any autoload commands in the PKG_ADD file, then
multiple functions in a .oct file will not work properly.  If the
autoload commands are missing, then something went wrong when the
PKG_ADD file was constructed.  Are you sure the PKG_ADD file you have
installed is actually from 2.9.6?

Also, Octave no longer uses the ls-R file, so it seems you still have
some files left over from an earlier installation.  I'd recommend
removing all that you can find and doing a fresh install.

Those files are just used during the build process to keep track of
some information extracted from the source files.  They are not
intended to be installed.
