I could build libgd ok, but ran into an error building gnuplot
(see below). And while we're at it, is it ok that the gnuplot
prefix is <gretl.app-skeleton-dir>/Gretl_Folder while the
"export PATH=..." line for building gretl is something different
(to my unknowledgeable eyes)?
Oops, no, it should be Gretl.app. I've now fixed that in
build.pdf.
g++ -g -O2 -L/usr/X11R6/lib -o gnuplot...
Undefined symbols:

Urgh, I think I've read about this somewhere. I believe what's
happening is that current OS X installs some BSD thingy that's not
really libreadline but that claims to be (via a symlink perhaps).
So when you try to build a third-party program (such as gnuplot)
that wants to link against libreadline (if it's available) you get
a mess of undefined symbols.
I think the options here are:
1) install readline and readline-shlibs via Fink; or
2) add the flag --with-readline=builtin when configuring gnuplot
