WARNING: YAML.pm is not installed. This is not a full dependency, but is highly
recommended; in particular, the scaffolded Dancer app being created will not be
able to read settings from the config file without YAML.pm being installed.
To resolve this, simply install YAML from CPAN, for instance using one of the
following commands:
cpan YAML
perl -MCPAN -e 'install YAML'
curl -L http://cpanmin.us | perl - --sudo YAML
