Perl core is not only interpreter but also core modules - CGI, Module::Build, CPAN,... Some of these modules have dual life in core and in their own package, because it's much easier to update them (for maintainer).
You probably have installed Perl. If not, it's not good idea to test it ;-)
How to test
- Do you have perl-core?
rpm -q perl-coreGreat. This will require core modules, so they are installed too eg. perl-CGI, perl-Module-Build.
- Will be perl or 'perl(Some::Module)' installed in yum update? Did
yum updatepassed? Than dual life packages don't conflict with core package. No missing dependencies or NVR problems.
- Do you have only perl because you like minimal installation? Great, than you can check if update doesn't pull in any other un-needed dependencies.
- Clean yum update without warnings, no NVR problems, no new useless dependencies in case of minimal Perl installation.
