Comment 6 for bug 1269877

The issue here doesn't have anything to perl-MySQL-DBD or perl in general.

I just experienced exactly the same issue on a RedHat 6.5 system. All perl modules of any note installed and I get the same error message about perl-MySQL-DBD.

[root@perr2dbph01 ~]# pt-deadlock-logger --host=localhost --socket=/var/lib/mysql/mysql.sock --user=root --password=mysql@dm1n --dest D=admin,t=deadlocks --daemonize --run-time 1h --interval 30s

When I installed the mysql-libs package the following magic happens:
[root@perr2dbph01 ~]# yum install mysql-libs

As you can see it suddenly started working perfectly.

As I see it the core issue here is the requirement for what amounts to a shared-compat library because the percona toolkit items are looking for old libraries. Update the tools to use the newer libraries and this all goes away. This is a pain, especially since Percona no longer supplies a shared-compat rpm.

Hope this helps.
