public class BindException extends SocketException

Signals that an error occurred while attempting to bind a socket to a 
local address and port. Typically, the port is in use, or the requested 
local address could not be assigned.

something else may be listening, the question is: which port. It may 
just be an accidental clash.

try passive="true"

I've just tweaked <ftp> in the repository to not strip out so much of 
the caught exception, so a -v run will include more diagnostics. Check 
it out and rebuild ant if you want to do more debugging.
