Bug#808430: perl-modules-5.22: after the upgrade to perl 5.22, the Module::Build module is no longer present

[Vincent Lefevre]

Package: perl-modules-5.22
Version: 5.22.1-2
Severity: serious

After the upgrade to perl 5.22, the Module::Build module is no longer
present. With perl 5.20, it was present in both perl-modules and
libmodule-build-perl. After the upgrade, it is no longer in
perl-modules-5.22, and libmodule-build-perl automatically gets
removed by aptitude because it is no longer recommended, so that
the module is no longer present at all.

Other modules might be affected by the same problem. I could see
many packages that were removed, but I don't know which ones were
redundant.

The upgrade should not remove any module that can still be useful
(perhaps unless this is announced in the NEWS.Debian file, so that
the user has a chance to reinstall what needs be before he's
wondering what's wrong).
