I would agree. I have the same behavior in a Redhat 8 development system, so it's not a problem with the Centos build.

We’ve been seeing the symptom here, too, but the trigger was somewhere inside a thousand-like shell script. We do similar things to what the above test does, so we have all of those packages installed in our default install except for perl-libwww-perl. Note that the symptom doesn’t happen on “yum upgrade”, only on certain other operations. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

So, I suspect your interpretation doesn't fit the facts. David K ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos Not seeing that here but it appears you are running newer versions of at least perl-DBD-MySQL, perl-DBD-SQLite and perl-DBI (snipped from "yum list installed" on my CentOS 8 VM after running "yum update"): perl-DBD-MySQL.x86_64 4.023-6.el7 @anaconda perl-DBD-SQLite.x86_64 1.39-3.el7 @anaconda perl-DBI.x86_64 1.627-4.el7 @anaconda What repo are you pulling the listed packages from? Is it the same repo as for perl? I'm getting: root@bend ~]# perl -v This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi for perl. Since you said you're running 5.26.3 but from a standard repo which doesn't match what I'm seeing (5.16.3), I'm thinking your mismatches are due to the listed modules being built against a newer version of perl.
