As the above message describes, you need to *already have* libzmq in
order to build pyzmq from source, and if you install it to a
non-default location (presumably necessary if you don't have root
access) you will need to add a `python setup.py configure
--zmq=/path/to/libzmq/prefix` step prior to building. The easiest way
to install libzmq is `brew install zeromq` with homebrew, but it's
just a simple `./configure --prefix=foo && make && make install`
package if you want to do it yourself.
That said, I don't know why your Python doesn't see the appropriate
OSX egg, which includes libzmq, but you might try fetching it
If you are on 10.6, then it might be ignoring the 10.7 egg, but I'm
not sure that it won't actually work.
