RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ This bug was initially created as a clone of Bug #612563 +++

Description of problem:

/usr/bin/cpan strongly suggests to install "Digest::SHA".

Fedora's perl-CPAN, however doesn't depend on "perl(Digest::SHA)", 
i.e. users will be tempted to manually install Digest::SHA

Note: We are talking about Fedora+cpan users. It's this group of users, which at least I consider to be specially susceptible to using cpan instead of using rpm-packaged perl-modules.

Version-Release number of selected component (if applicable):
perl-5.10.1-112.fc13.x86_64

How reproducible:
Always

Steps to Reproduce:
1. yum install perl-CPAN
2. /usr/bin/cpan
3. get Test
  
Actual results:

cpan issues a "strong suggestion":
...
  CPAN: checksum security checks disabled because Digest::SHA not installed.
  Please consider installing the Digest::SHA module.

Expected results:
cpan not to issue such warning and to behave "safe by default".
