I checked path and it looks fine
there is a libzmq.dll at PATH folder.
The thing that is annoying is, it works find without wsgi.
some code like.
import zmq
context = zmq.Context()
# Socket to talk to server
print "Connecting to hello world server"
socket = context.socket(zmq.REQ)
socket.connect ("tcp://localhost:5555")
works just fine
