After that, just run:

print $client->get_data();


The Perl Client module functions always return the command summary  
(i.e. the brief message which the C clients send to stderr, which is  
the one you saw in your tests). The most recently returned data, if  
any, are always accessible via the get_data() member function. The  
reason for this somewhat obscure design is that some commands do not  
return data, but only a summary. For the sake of consistency, these  
functions would have to return undef if we'd use the data proper as a  
return value throughout.

BTW the test script test.pl runs each function at least once. It is a  
good resource for finding out how these functions work.

regards,
Markus
