Tango / Network Example compilation failure

[Gregor Kopp]

Hi, I want to start out with network programming with dmd 1.020 on 
Windows XP and Tango (installed with dsss net install tango)

If I try to compile this example here:
http://www.dsource.org/projects/tango/wiki/SocketServerExample

I get the following error messages:

server.d(38): class tango.net.SocketConduit.SocketConduit member write 
is not accessible
server.d(51): class tango.net.SocketConduit.SocketConduit member read is 
not accessible

Can anyone tell me what this means?
