I think this is because of a missing runtime dependency on
libautobox-perl. It's a build dependency so the build time test suite
doesn't warn, and it goes away when I install the other package.
The module does
package autobox::dump;
use base 'autobox';
which somewhat surprisingly doesn't fail when autobox is missing.
Apparently the package declaration populates the "parent stash" just
enough to make it look nonempty. Consider:
$ perl -e 'package foo; use base "bar"'
Base class package "bar" is empty.
(Perhaps you need to 'use' the module which defines that package first,
[...]
$ perl -e 'package bar::foo; use base "bar";'
$
However, the $class->SUPER::import() call later does generates a warning
with Perl 5.40 because the superclass is really empty.
Not sure if this should be severity:serious but at least it's easy to
fix by adding a Depends: libautobox-perl.
Hope this helps,
