lots of pdl messages on Xenial Negative repeat count does nothing

Naively installing the yakkety package does not work.
5.22.1-9 It would help if the perl depencency would just be a little lower.
And there is a problem with install-docs when trying that on xenial.

sudo dpkg --install pdl_2.016-4_amd64.deb

Alternatively, change the following code:

diff -r1.1 /usr/lib/x86_64-linux-gnu/perl5/5.22/PDL/Core.pm
1546,1547c1546,1549
< my($s) = ',' x ( ($dim > $pdl->getndims) ? ($pdl->getndims) : ($dim) );
< $s .= '*1,' x ( $dim-$pdl->getndims );
---
> # Avoid negative repeat count warning that came with 5.21 and later.
> my $dim_diff = $dim - $pdl->getndims;
> my($s) = ',' x ( $dim_diff > 0 ? $pdl->getndims : $dim );
> $s .= '*1,' x ( $dim_diff > 0 ? $dim_diff : 0 );

This patch was in PDL as of 26 Feb 2015, and main-released to CPAN as 2.008 on 24 May 2015. Seeing as it's 2021 and CPAN's PDL is 2.038, can this bug be closed?
