Hi there!

Recently there were a number of days that the perl-tester Docker image did not build properly. It is always a bit of an issue with it, because there quite a few moving parts. Parts where the dependency isn't fixed. e.g. in most of the cases it installs the most recent version of the modules from CPAN. Which mean any release of any module might break the whole build process. This time, however, the source of the problem was the new release of App::cpm , the tool used to install the CPAN modules. As often the case the new release was intended to improve things: cpm v1: making installs stable , but it broke the build on some of the older versions of Perl just by increasing the minimum version of Perl required.

One solution would be to fix all the dependencies, both tooling and the modules we install, but then someone would need to keep track of changes (the way dependabot does) which is probably way too much work for the few people who contribute to this…
