Hmmm...... so it seems not to be linking with libpgplot.a.  Odd.

I notice on my computer that the pgplot library is called
libpgplot_iff.a and that the Makefile in src/lib/ has this line:

PGPLOT_LIBS = -L/usr/local/share/ifeffit/pgplot -lpgplot_iff -lpng -lz -lX11

I also see that Matt's PGPLOT_install script changes one of pgplot's
files to use the installation location specified in PGPLOT_install as
default location (i.e. the one that would be specified by setting the
PGPLOT_DIR environment variable).  The script then renames the library
to have the "_iff".

There are a number of ways to address.  Here is one relatively simple
suggestion:

  1. cd to the location of libpgplot.a on your computer

  2. make a symbolic link to libpgplot.a like so:
        ln -s libpgplot.a libpgplot_iff.a

  3. set the PGPLOT_DIR environment variable to the directory
     containing libpgplot.a.  This can be done either typing
        export PGPLOT_DIR=/location/of/pgplot
     at the commend line or putting it in a login script to make it
     permanent.  (Of course, replace /location/of/pgplot with the
     correct thing on your computer.)

  4. cd back to the location of the ifeffit source and try again to
     build it.

All that is, of course, untested on my end.  But I think it should
work.  If not, we'll keep trying until we figure it out!
