This just reminded me there is another alternative as well that works
cross-platform, does not require the pkg-config package, and (unlike
plplot_libtool) does not hijack the command-line .  Please have a look at
plplot-config.  This was written by Maurice LeBrun as a convenient front-end
for plplot_libtool, and it apparently works quite well.

On my system:

plplot-config --cflags  --libs

echos back

-I/usr/local/plplot_at/include -I/usr/X11R6/include
-L/usr/local/plplot_at/lib /usr/local/plplot_at/lib/libplplotd.so
/usr/lib/libfreetype.so /usr/local/plplot_at/lib/libcsirocsa.so
/usr/local/plplot_at/lib/libcsironn.so -lqhull -lm -ldl -Wl,--rpath
-Wl,/usr/local/plplot_at/lib -Wl,--rpath -Wl,/usr/local/plplot_at/lib

Of course --cflags and --libs can be used separately and there are
--with-c++, --with-g77, and --with-tcl options as well that modify the
--cflags and --libs output.

So it has all the benefits of plplot_libtool (well-tested cross-platform
support using exactly the same libtool script that is automatically used by
make check to build the examples in the build tree) without the drawback of
hijacking the command line.

I had completely forgotten about this script, but now I am reminded of it I
intend to change over the various Makefile.examples.in files to use it to
replace the raw plplot_libtool commands found there.

Don't hold the cvs snapshot tarball for this since it is only a design issue
and has no direct practical impact.  This change will take me some extra
time today because I notice that plplot-config.in does not yet take
advantage of the TCLINCCMD, TKINCCMD, and INCLUDE_DIR_CMD configuration
variables.
