$ sudo certbot certonly --nginx -d somedomain

Could not choose appropriate plugin: The nginx plugin is not working; there may be problems with your existing configuration.
The error was: MisconfigurationError('Error while running nginx -c /usr/local/etc/nginx/nginx.conf -t.\n\nnginx: [emerg] open() "/usr/local/etc/nginx/nginx.conf" failed (2: No such file or directory)\nnginx: configuration file /usr/local/etc/nginx/nginx.conf test failed\n',)

I can work around this by specifying --nginx-server-root /opt/local/etc/nginx however it seems like the MacPorts copy of certbot-nginx should use that as its default value.
