perl.prov mistakenly adds embedded Parse::Yapp::Driver

[jirislaby]

Math-Calc-Units uses Parse::Yapp::Driver and contains its generated grammar:
https://metacpan.org/release/SFINK/Math-Calc-Units-1.07/source/Units/Grammar.pm

There is:

package Math::Calc::Units::Grammar;
use vars qw ( @ISA );
use strict;
 
@ISA= qw ( Parse::Yapp::Driver );
#Included Parse/Yapp/Driver.pm file----------------------------------------
{
#
# Module Parse::Yapp::Driver
#
# This module is part of the Parse::Yapp package available on your
# nearest CPAN
...
 
package Parse::Yapp::Driver;
...
$VERSION = '1.04';

perl.prov generates:

perl(Parse::Yapp::Driver) = 1.04

It should likely (somehow) ignore embedded packages. Or at least provide a blacklist feature (to supply Parse::Yapp::Driver in this very case).

Patches welcome.

Until then, use the filtering mechanism(s) available: https://rpm-software-management.github.io/rpm/manual/dependency_generators.html

Those generators are something we would happily hand over to a Perl community maintained perl-rpm-macros package.

For openSUSE we use patches which change source so that it's no longer detected (usually with a line break or similar). That's ugly and thus never reported upstream. Maybe we can add a keyword for these cases (like # no-rpm-provides) which upstream authors would accept?
