--- Comment #3 from Petr Pisar ppisar@redhat.com --- Could you please declare dependencies on all used Perl modules in Makefile.PL (strict, Config; ExtUtils::Constant or File::Copy and File::Spec)?
The same applies to modules used when running tests (./lib and ./t directories). We in Fedora declare all dependencies including CORE modules.
You can use "tangerine" tool from the same-named RPM package for rough estimation what modules could be used.
