 Here's what happens:

 Oh, I think that I saw a similar problem once already, even though it was
 in a slightly different context. I think that I had problems when doing an
 out-of-source build.

 This code comes from {{{docs/Makefile.in}}} which includes:
 {{{
 gnuplot.texi $(srcdir)/gnuplot-eldoc.el $(srcdir)/gnuplot-eldoc.elc:
 $(srcdir)/doc2texi.el $(srcdir)/gnuplot.doc
   @echo "Creating texinfo and eldoc strings file"
   @if test "$(EMACS)" != no; then \
      test "$(top_srcdir)" = "$(top_builddir)" || echo "COPYING
 GNUPLOT.DOC" ; \
      test "$(top_srcdir)" = "$(top_builddir)" || cp $(srcdir)/gnuplot.doc
 . ; \
      $(EMACS) -batch -l $(srcdir)/doc2texi.el -f d2t-doc-to-texi ; \
      echo "Compiling gnuplot-eldoc.el" ; \
      $(EMACS) -batch --eval='(byte-compile-file "gnuplot-eldoc.el")' ; \
   else \
      echo "No emacs found - cannot create texinfo file" ; \
   fi
 }}}

 First of all, I have no idea why this fails. Second, independent of
 whether or not it fails, the code should not be executed as long as
 docs/gnuplot.texi is present.
 {{{
 $(srcdir)/gnuplot-eldoc.el $(srcdir)/gnuplot-eldoc.elc:
 $(srcdir)/doc2texi.el $(srcdir)/gnuplot.doc
 }}}

 But to start with, I believe that one of the problems might be that emacs
 is found (the one provided by the system, not the one provided by
 macports). Can you please try to set
 {{{
 export EMACS=no
 }}}
 then clean and reinstall gnuplot package just to see if this helps?

 I once wrote the following patch to assist with out-of-source building
 without emacs, but I need to remember what it does and most probably I
 need to change it anyway.

 All-in-all: I'm confused.
