The commands are of the form

  autoload ("fcn", "$octlibdir/file.oct");

(with the actual value of $octlibdir substituted when the PKG_ADD file
is generated) so how is it that octlibdir changes when you run make
install?  Are you using a value of $prefix at install time that is
different from the one used at configure time?  If so, I'd suggest
using $DESTDIR for this purpose instead of changing $prefix.  Is there
some reason you can't do that?  Do the package tools assume it is OK
to change prefix at install time?

Maybe a better solution would be to generate the lines

  autoload ("fcn", strcat (strrep (octave_config_info ("octlibdir"),
                                   octave_config_info ("octlibdir"),
                                   OCTAVE_HOME)),
                           filesep,
                           "file.oct");

instead.  Then this would also work if someone moved their installed
copy of Octave and set OCTAVE_HOME appropriately.
