-  # we use locally installed cpan modules instead of travis' builtin 'homebrew' perl support
-  # The homebrew variation does not work for us, since:
-  #   * it is built without threading
-  #   * the 'libvirt' plugin requires Sys::Virt, which is not available via cpan anymore - thus we need to install the Debian package 'libsys-virt-perl', which was built with threading
