in thread module-starter command not found after installation

That means that you need to install a YAML module or a JSON module. CPAN will let you choose which module that you want. I've had problems with YAML, so I always choose YAML::Syck. So, sudo to cpan, then
cpan> install YAML::Syck cpan> o conf init yaml_module #choose YAML::Syck cpan> o conf commit
