[zeromq-dev] problem building pyzmq

1) So this thing about needing to download a stable release refers to a 
stable release of pyzmq, not 0mq, right?

2) Is it correct that the latest stable release of 0mq is 2.0.10?

3) Where do I download a stable release of pyzmq? The only instructions 
I can find for downloading pyzmq say to download from git, yet you are 
telling me that git only has development releases.

4) How can I figure out what version of pyzmq I have installed? (I am 
new to python.)

The good news is that I finally got cpython installed and was able to 
install pyzmq.
