Bug#986147: libpgplot-perl: pgplot demo in pdl does not work

[Dr. Johann Pfefferl]

Package: libpgplot-perl
Version: 1:2.24-1+b2
Severity: important

Dear Maintainer,

   * What led up to the situation?
   Installed this package and pdl and wanted to use the pgplot
   functionality. On Debian Buster this worked as expected.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     I called pdl and then I entered the command ´demo pgplot´
   * What was the outcome of this action?
   I got an error message.
   Undefined subroutine &PDL::Demos::PGPLOT_demo::run called at /usr/bin/perldl line 453.
 at /usr/bin/perldl line 453.
	main::demo("pgplot") called at (eval 63) line 4
	main::__ANON__() called at /usr/bin/perldl line 719
	eval {...} called at /usr/bin/perldl line 719
	main::eval_and_report("demo 'pgplot'\x{a}") called at /usr/bin/perldl line 655
	main::process_input() called at /usr/bin/perldl line 675
	eval {...} called at /usr/bin/perldl line 675

   * What outcome did you expect instead?
   A graphical plot pops up on the desktop.
