docker_cpu doesn't work anymore

[Magneticdud]

After some munin update i'm not able to run the docker_cpu plugin anymore. Maybe it could be happened a year ago or more, i didn't check the munin page in long time

I get this in the logs

Error output from docker_cpu:
syntax error at /etc/munin/plugins/docker_cpu line 103, near "print"
Execution of /etc/munin/plugins/docker_cpu aborted due to compilation errors.

Unfortunately, I have no knowledge of Perl to understand what's going on
