The following targets for installing and uninstalling .oct files are
in the src/Makefile.am file:

  if AMCOND_ENABLE_DYNAMIC_LINKING
  install-oct:
          $(top_srcdir)/mkinstalldirs $(DESTDIR)$(octfiledir)
          if [ -n "`cat DLD-FUNCTIONS/PKG_ADD`" ]; then \
            $(INSTALL_DATA) DLD-FUNCTIONS/PKG_ADD 
$(DESTDIR)$(octfiledir)/PKG_ADD; \
          fi
          cd $(DESTDIR)$(octlibdir) && \
          for ltlib in $(DLD_FUNCTIONS_LIBS); do \
            f=`echo $$ltlib | $(SED) 's,.*/,,'`; \
            dl=`$(SED) -n -e "s/dlname='\([^']*\)'/\1/p" < $$f`; \
            if [ -n "$$dl" ]; then \
              $(INSTALL_PROGRAM) $$dl $(DESTDIR)$(octfiledir)/`echo $$f | 
$(SED) 's,^lib,,; s,\.la$$,.oct,'`; \
            else \
              echo "error: dlname is empty in $$ltlib!"; \
              exit 1; \
            fi; \
            lnames=`$(SED) -n -e "s/library_names='\([^']*\)'/\1/p" < $$f`; \
            if [ -n "$$lnames" ]; then \
              rm -f $$f $$lnames; \
            fi \
          done

  uninstall-oct:
          for f in $(OCT_FILES); do \
            rm -f $(DESTDIR)$(octfiledir)/`echo $$f | $(SED) 's,.*/,,'`; \
          done
          rm -f $(DESTDIR)$(octfiledir)/PKG_ADD
  endif
  .PHONY: install-oct uninstall-oct

First, is AMCOND_ENABLE_DYNAMIC_LINKING defined on your system, and are
these rules copied to the Makefile in your build tree?

If so, can you please investigate why they are not working properly?

The idea is that libtool will install the .la and .so (or .dll, or
whatever) files in the normal location for library files, then the
shell commands in the install-oct rule will look at the .la file and
copy the correct file over to the

What part of this process is failing on your system.

Also, what is the value of $(octlibdir) on your system, and are you
using that directory for installing other libraries?  If so, then to
avoid clashing with other files, we may have to modify this
procedure so that the .la and .so (or .dll, or whatever) files are
installed to a separate directory first instead of in $(octlibdir).
