Oops, no, it should be Gretl.app.  I've now fixed that in 
build.pdf.

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
