Some parts of the HTTP spec are ambiguous and left to implementation.  
In this specific case, error 411 means the server is saying that you  
are not sending a necessary content-length header, which is required  
for POSt requests whether there is any content or not. It may be that  
LWP doesn't provide the header if there is no content. Did you inspect  
the request to verify that the content-length header is indeed being  
sent?

If the header is indeed being sent, the server might be choking on a 0  
length. Send bogus data to see if that helps.
