Hello Ed, here is the amended install instructions for Arch Linux, see below. No errors are reported and all packages are installed OK. Perlbrew is not used for now.
Even a graphics window with the desired output of imag (sin(rvals(200,200)+1)) pops up quickly during install of sudo cpanm PDL::Graphics::Simple. which is encouraging. However, pdl> use PDL::Graphics::Simple Can't locate PDL/Graphics/PGPLOT/Window.pm in @INC (you may need to install the PDL::Graphics::PGPLOT::Window module) (@INC entries checked: /home/th6mas/perl5/lib/perl5/5.38.0/x86_64-linux-thread-multi /home/th6mas/perl5/lib/perl5/5.38.0 /home/th6mas/perl5/lib/perl5/x86_64-linux-thread-multi /home/th6mas/perl5/lib/perl5 /usr/lib/perl5/5.38/site_perl /usr/share/perl5/site_perl /usr/lib/perl5/5.38/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/5.38/core_perl /usr/share/perl5/core_perl) at /home/th6mas/perl5/lib/perl5/PDL/Graphics/Simple/PGPLOT.pm line 28. reading through https://metacpan.org/pod/PDL::Graphics::Simple#SUPPORTED-GRAPHICS-ENGINES we are in my Arch installation in the Gnuplot world where things work fine. How then to direct the interactive pdl shell not to use PGPLOT but Gnuplot instead?
