Re^3: Missing sub-module of PDL::Graphics::Simple

Insights, insights, insights :-) I don't know if there is an easy fix for this but I discovered that in my perlbrewed perl 5.36.1 there is a gnuplot binary, Version 5.4 patchlevel 6 last modified 2023-02-09, whereas mine built and installed in /opt/local with macPorts is Version 5.4 patchlevel 8 last modified 2023-06-01. The versions themselves are not important, but what is, is that 'unknown' terminal type is coming from the perlbrew version, as in:

  Terminal type is now 'unknown'

  set term x11
         ^
  unknown or ambiguous terminal type; type just 'set terminal' for a list

  WARNING: Error during initialization

The PDL::Graphics::Gnuplot build Make is not using my macPorts gnuplot but this one in perlbrew that may be crippled. Also, this perlbrewed version is not honoring GNUTERM='x11' in zsh. Simply relying on $PATH won't work as 'which gnuplot' already returns the one in /opt/local while the Make in PDL::Graphics::Gnuplot is not. It looks like fetching and building Alien::Gnuplot with cpanm is the source of that gnuplot binary in perlbrew. I'm not sure what the best fix is, to delete all traces of gnuplot in perlbrew or to explore its config. It strikes me as the better solution is to use the macPorts version which probably contains a full implementation of gnuplot. Comments please?
