hmm. That hour or so became somewhat expanded because I was having trouble
with both libtool and automake in dealing with the strange octave naming
conventions for its interface shared objects.  But the new libtool method
now works for me (at least in the install directory).

N.B.  There is a g++ header file name clash with our own directory tree.

The compile command includes the normal -I../.., but one of the includes
buried deep in the include structure does #include <new> (or something like
that) which finds our ../../new directory and crashes.  Getting rid of
-I../.. solved the problem, but I don't know how to do that in libtool.  The
workaround I finally used was to mv the PLplot new directory (which
currently is filled with nothing important) somewhere else.  If you have a
similar problem do the same for now.  We can think of a permanent solution
later (such as removing new from cvs or renaming it) if you like this
libtool approach.  I think we will want a permanent solution in any case
because our "new" directory tree name is just an accident waiting to happen
because of that -I../..

The Makefile.am changes should be considered a first cut, and I am sure
there are much more elegant libtool methods for doing the same job.

I don't know how to use octave in the build tree so that is untested (although
I tried to support it).

I did test octave examples in the install tree, and they worked fine.

There are still some cross-platform issues.  For example, the mv and copy
commands which are used to create the install tree plplot_octave.oct and
build tree plplot_octave.oct assume the original file has
a suffix of .so which won't work on all unix platforms.  (I tried to
change that with -shrext, but I couldn't get it to work.)  There are ways
around this (such as grepping in the *.la file), but I would prefer to
find out how to make -shrext work.

Please test this on your Linux systems for now and see how you like it.
