** SOME PERL MODULES ARE MISSING ******************************

If you know where perl can find the missing modules, set
the RAKULIB environment variable accordingly. Otherwise
just proceed and the missing modules will be installed
automatically.

To force the system to download missing raku modules, you can
do a `zef --debug --/test --deps-only --test-depends --force-install install .` before running `$GMAKE`
