Each time I install a new perl5 release for testing,
I pull in a couple of additional modules, tasks and bundles
to feel at home.
Bundle::CPANxxl and Test::Reporter::Transport::Metabase
are among these.
I use the CPAN module and have a couple of special rules
in my distroprefs directory (o conf prefs_dir).
Distroprefs can apply local patches, fine-tune the build
environment and prevent installations from turning interactive.
Although my CPAN configuration in ~/.cpan/CPAN/MyConfig.pm
is shared among all perl instances, newly installed perls
seem to ignore my distroprefs, however.
Only after the Bundle::CPANxxl modules are installed,
distroprefs seem to be effective.
I have observed this with new builds of perl-5.26.0 on
Debian GNU/Linux 8.
Now here is my question:
If indeed a missing module prevents CPAN.pm from using its
distroprefs, what is a minimal set of non-core modules
that need to be installed in order for distroprefs to be working?
I would like to reduce the risk of bootstrapping headaches
by installing those first.
