In theory, once you've installed the Perl UPnP prereq's, the script 
would automatically find the backend on the network, then connect to the 
backend, then ask it for the database information (hostname, port, 
username, password, etc.).  (Though I can't guarantee that it would 
actually work at this point as I don't think either the bindings or the 
"common" scripts support prompting for a PIN, so the UPnP connection 
would fail.)

Yeah, MythTV was updated to require users to specify a valid HOME 
directory, but the Perl bindings haven't been updated.  I'm pretty sure 
they would actually allow HOME=/ as long as the config.xml actually 
exists in /.mythtv/ (just tested--they do on mine for both mythrename.pl 
and optimize_mythdb.pl).  In the above test, the file 
/.mythtv/config.xml must not exist or the directory /.mythtv must not be 
readable or executable for the user running the script.

So, the error message is basically telling you how to get the bindings 
to work (though the "fix" wouldn't work with the rest of Myth and, 
really, the right fix is to fix the HOME environment variable).
