libtest-diaginc-perl 0.010-2 (i386 binary) in ubuntu lunar

 Assuming you shipped your module to CPAN with working tests, test failures
 from CPAN Testers[1] might be due to platform issues, Perl version issues or
 problems with dependencies. Test::DiagINC helps you diagnose deep dependency
 problems by showing you exactly what modules and versions were loaded during a
 test run.
 .
 When this module is loaded, it sets up an END block that will take action if
 the program is about to exit with a non-zero exit code or if
 $test_builder->is_passing|Test::Builder/is_passing is false by the time the
 END block is reached. If that happens, this module prints out the names and
 version numbers of non-local modules appearing in %INC|perlvar/%INC at the
 end of the test.
