Wow Pete!
Nice sideloading instructions. Yes that certainly fixes things.
I will try the suggested Debian perl email address.

Subject: Re: [Pdl-general] PDL pgplot Ubuntu/ debian package
I'm not an expert in Ubuntu packaging, but was at least able to revert
to the Xenial packages with the following steps.
mkdir libpgplot-perl
cd libpgplot-perl
wget
http://archive.ubuntu.com/ubuntu/pool/multiverse/libp/libpgplot-perl/libpgplot-perl_2.21.orig.tar.gz
wget
http://archive.ubuntu.com/ubuntu/pool/multiverse/libp/libpgplot-perl/libpgplot-perl_2.21-5build1.dsc
wget
http://archive.ubuntu.com/ubuntu/pool/multiverse/libp/libpgplot-perl/libpgplot-perl_2.21-5build1.debian.tar.xz
dpkg-source -x libpgplot-perl_2.21-5build1.dsc
cd libpgplot-perl-2.21
perl -pi -e s/libpng12/libpng/ debian/control
# some additional packages my system needed for debuild to work
sudo apt-get install gfortran libextutils-f77-perl pgplot5 chrpath debhelper
# will end with a fatal error, but the deb is built successfully
debuild
cd ../..
sudo apt-get purge libcpgplot0 libpgplot0 -y
sudo apt-get install ./libpgplot-perl/libpgplot-perl_2.21-5build1_amd64.deb
