You should be able to download PDL-Graphics-PLplot-0.40.tar.gz from CPAN, then: tar -xvzf PDL-Graphics-PLplot-0.40.tar.gz cd PDL-Graphics-PLplot-0.40 perl Makefile.PL make make test make install It is also possible that a CPAN install from the perl 'cpan' tool would work. > > The current method of specifying HAVE_PDL_GRAPHICS_PLPLOT_40 is to set > either -DHAVE_PDL_GRAPHICS_PLPLOT_40=ON or -DHAVE_PDL_GRAPHICS_PLPLOT_40=OFF > (the default) as one of the cmake options. > I would like to replace that crude control method by one that automatically > tests the version of PDL-Graphics-PLplot that is available and sets > HAVE_PDL_GRAPHICS_PLPLOT_40 appropriately.

Do you have such a command to suggest to me?

I just uploaded a new version to CPAN which should support this. Now: perl -MPDL::Graphics::PLplot -e 'print "$PDL::Graphics::PLplot::VERSION\n"' should work, printing '0.41'. A test of 0.41 or greater should suffice, as I know I'll be releasing 0.42 soon. > > I am very pleased to hear that you are actively working on the Perl/PDL > aspects of PLplot again.
