check-http.rb --port doesn't work

What can I say...

```
root@fserver0001:/# /opt/sensu/embedded/bin/check-http.rb --port 888888888888 -u http://192.168.1.35
CheckHttp OK: 200, 970 bytes
```

I have a service on port 5004. If I stop this service...

```
root@fserver0001:/# /opt/sensu/embedded/bin/check-http.rb --port 5004 -u http://192.168.1.35
CheckHttp OK: 200, 970 bytes
```
