[IPython-dev] pyzmq: kernel.py doesn't work

[Brian Granger]

Ondrej,

I have fixed the kernel examples to work with the updated APIs:

http://github.com/ellisonbg/pyzmq/commit/75f61fad9e0ce56f6da76a9ad516f3ba68eb4f44

WARNING:  a lot of work has been done on 0MQ itself lately and PyZMQ
requires teh latest master of 0MQ itself, so you may have to update
your ZMQ build.  Once the next version of 0MQ is released, I will
probably start to release PyZMQ in synch with 0MQ.

Cheers,

Brian
