Solutions

1. Reinstall the fusuma plugin gem (gem install fusuma-plugin-NAME) so its .gemspec file is present in the gem directory.
2. Repair a corrupted gem installation with gem pristine fusuma-plugin-NAME, or uninstall and reinstall the plugin.
3. Ensure the plugin gem name follows the fusuma-plugin-* convention so its gemspec sits next to its lib directory.
