Yep, gnuplot is there, and was found by configure also. Also, when I issue a plot command octave actually opens a gnuplot window, but fails trying to invoke __gnuplot_plot__. And furthermore I am also missing other funtions such as max and min. Since these, like __gnuplot_plot__, do not have a .oct file named after them I suspect octave fails to extract commands from inside .oct files. Maybe an issue in the way octave dynamically links the .oct files? On OSX it uses dyld and not dlopen as I suspect is used on Linux.

Do you have gnuplot installed?

I wanted to build an octave version against the native gcc4.0.1 on  
Mac Os 10.4 Tiger. I had some trouble configuring 2.1 so I tried 2.9,

4.2.0 instead, substituting -lreadline in configure with /usr/local/ 
libreadline.dylib to circumvent BSDs malicious libreadline and  
changing <readline/readline.h> to <readline.h> in the include at one  
point so octave could acess the internal readline functions).

Running I find that I can't use plot (__gnuplot_plot__ undefined).  
Further investigation leads me to beleive that simply no functions  
that are contained within an .oct-file but don't carry the same name  
as this can be called. For example min and max are also defined  
(seemingly defined inside minmax.oct). I could not find any docs on  
how those functions are resolved.

Any Ideas? I have heard before that octave 2.9 was compiled on Tiger  
before rather cleanly (except for the same readline troubles), anyone  
who has done this any tips?
