Bug#914013: perl: missing-depends-on-sensible-utils

[Niko Tyni]

Package: perl
Version: 5.28.0-3

As prompted by lintian:

E: libperl-dev: missing-depends-on-sensible-utils usr/lib/x86_64-linux-gnu/libperl.a
E: perl-modules-5.28: missing-depends-on-sensible-utils usr/share/perl/5.28.0/Pod/Perldoc/ToTerm.pm
E: libperl5.28: missing-depends-on-sensible-utils usr/lib/x86_64-linux-gnu/libperl.so.5.28.0
E: libperl5.28: missing-depends-on-sensible-utils usr/lib/x86_64-linux-gnu/perl/5.28.0/CORE/patchlevel-debian.h
E: libperl5.28: missing-depends-on-sensible-utils usr/lib/x86_64-linux-gnu/perl/5.28.0/Config_heavy.pl
E: perl-base: missing-depends-on-sensible-utils usr/bin/perl
E: perl-base: missing-depends-on-sensible-utils usr/bin/perl5.28.0
E: perl-base: missing-depends-on-sensible-utils usr/lib/x86_64-linux-gnu/perl-base/Config_heavy.pl
E: perl-debug: missing-depends-on-sensible-utils usr/bin/debugperl

This is a result of us building with -Dpager=/usr/bin/sensible-pager,
which ends up in the binary files, and patching Pod::Perldoc::ToTerm
to treat sensible-pager like 'less'. (The lintian check simply looks
for relevant strings in the binary packages, skipping /usr/share/doc
and /usr/share/locale.)

It looks to me like

- patchlevel-debian.h, libperl.{a,so} and the statically linked binaries
  only have sensible-pager in a patch description, so false positives

- the Pod::Perldoc::ToTerm changes in debian/perldoc-pager.diff don't
  imply any kind of dependency on sensible-pager, so a false positive

The only relevant hit is Config_heavy.pl. The implied dependency (perl
default pager) should IMO be at most a recommendation, though I'd lean
on the side of a suggestion.

So I propose we fix this by adding Suggests: sensible-utils in perl-base
and libperl5.28, and overriding the rest.

Thoughts?
