Problem with findNearestNodes

Ciao to all,
I'm playing around with kenosis on my mac, python2.4 from fink... When 
calling findNearestNodes.
I get the following error:

   File "python/Peer2Pub.py", line 42, in ?
     nodes=n.findNearestNodes (nodeAddress=kenosis.randomNodeAddress (), 
serviceName="PubDB")
   File "/Users/ktf/foo/PHYSH_0_1_1_pre1/lib/fink/kenosis/node.py", line 
661, in findNearestNodes
     nodeAddressObjectNetAddressPairs = 
self.nodeKernel_._findNearestNodeAddressObjectNetAddressTuples(
   File "/Users/ktf/foo/PHYSH_0_1_1_pre1/lib/fink/kenosis/node.py", line 
729, in _findNearestNodeAddressObjectNetAddressTuples
     serviceName=serviceName)
   File "/Users/ktf/foo/PHYSH_0_1_1_pre1/lib/fink/kenosis/node.py", line 
834, in __findNodeNetAddress
     realQueue.put(resultTuple)
   File "/sw/lib/python2.4/Queue.py", line 88, in put
     self._put(item)
   File "/Users/ktf/foo/PHYSH_0_1_1_pre1/lib/fink/ds/dsqueue.py", line 
8, in _put
     bisect.insort(self.queue, item)

AttributeError: insert

Any idea? I guess it's something related to python 2.3/2.4 differences, 
because when I use python 2.3 I get a different error (still crashing 
though):
