Newbie: AttributeError: 'module' object has no attribute 'Client'

Hi all,

I am just getting started with Pyro4, so please forgive me if I am doing
something very stupid.
I want a client to register with a server, much like the chatter example,
which works nicely. However, my code gives the error :

AttributeError: 'module' object has no attribute 'Client'

The server:
import Pyro4
                 
class Server(object):
    def ping(self):
        return 'pong'
    def join(self, callback):
        self.callback = callback
        return "connected"
        
def main():
    try:
        with Pyro4.core.Daemon() as daemon:
            with Pyro4.naming.locateNS() as ns:
                uri = daemon.register(Server())
                ns.register("test.server", uri)
            # enter the service loop.
            daemon.requestLoop()
    except Pyro4.errors.NamingError, e:
        print e

if __name__ == "__main__":
    main()
    print "Done"

The client:

import Pyro4
from Pyro4 import threadutil
                       
class Client(object):
    def __init__(self):
        self.server = Pyro4.core.Proxy('PYRONAME:test.server')
        print self.server
    def start(self):
        print self.server.ping()
        self.server.join(self)
        while True:
            line = raw_input('> ').strip()
            if line=='/q':
                break
        
class DaemonThread(threadutil.Thread):
    def __init__(self, instance):
        threadutil.Thread.__init__(self)
        self.instance = instance
    def run(self):
        with Pyro4.core.Daemon() as daemon:
            daemon.register(self.instance)
            daemon.requestLoop()

client = Client()
daemonthread=DaemonThread(client)
daemonthread.start()         
client.start()
print('Exit.')

Output:

<Pyro4.core.Proxy at 0x18cd310, not connected, for PYRONAME:test.server>
pong
Traceback (most recent call last):
  File "C:\Users\schnef\workspace\clipserp\src\server\client.py", line 28,

    client.start()
  File "C:\Users\schnef\workspace\clipserp\src\server\client.py", line 10,
in start
    self.server.join(self)
  File "C:\Python27\lib\site-packages\Pyro4\core.py", line 149, in __call__
    return self.__send(self.__name, args, kwargs)
  File "C:\Python27\lib\site-packages\Pyro4\core.py", line 289, in
_pyroInvoke
    raise data
AttributeError: 'module' object has no attribute 'Client'

I get the same error on Windows with python 2.7 and on Debian with Python
2.6. I have Pyro 4.1.4 installed.
I am lost, so any help would be appreciated very much,

TIA

Frans
