PyZMQ >= 2.0.10

[minrk]

Cleaner error if pyzmq is missing or pre-2.0.10.

On import of IPython.zmq, an ImportError with a meaningful message will be raised if pyzmq is found to be older than the current dependency of 2.0.10.

This could be changed to 2.0.10.1, which fixes a memory leak in 2.0.10 - thoughts?

Hey,

I installed from the v2.0.10-1 tag in the pyzmq repo, but I get

In [1]: import zmq

In [2]: zmq.__version__
Out[2]: '2.0dev'

So the check in this pull request would preclude this from working... Is it a problem with that tag in pyzmq?

There isn't a v2.0.10-1 tag... Some things got a little confused when we briefly had 2.0.10-1, but changed it to 2.0.10.1. There was still a dangling (not tagged, no 'v') 2.0.10-1 branch, so I just removed that, and replaced it with a proper 2.0.10.1 branch pointing to the v2.0.10.1 tagged commit.

Can you checkout [v]2.0.10.1? ack reveals no instances of '2.0dev' in that revision that I can find.

'2.0dev' is the version string we are using for bugfixes in 2.0.x (aka maint in zeromq). '2.0dev' > '2.0.10', so assuming 2.0.x is up-to-date, then the check still evaluates correctly, because 2.0.x is indeed newer than 2.0.10.

OK, sounds good. Indeed, used that 2.0.10-1 branch.

Go ahead with the merge and I'm OK with making -1 the minimum required one: anyone running this stuff is building from source for now, and we might as well be sure they're running a good version... Go for the merge, thanks!
