Re^2: Do Pure Perl CPAN packages really need to use ExtUtils::Command::MM?
in thread Do Pure Perl CPAN packages really need to use ExtUtils::Command::MM?
I couldn't find a 'require version' or 'use version' line in the source code of Module::Build. There is only that single line in the changelog. You might ask schwern about it or send the maintainers a bug report. The documentation only says that since 5.6.0 all prerequisites are included in core, but works fine on 5.005.
Anyway, does that change much? Companies that still use a pre-5.6.0 versions are usually so conservative that they don't allow any modules from CPAN anyway
