I'm having several problems getting tests to successfully run under my fork (or vbuterin's pybitcointools, and I'm hoping someone with a combined Python / Bitcoin knowledge can provide some insight.
Here's the error message (as submitted to #145):
======================================================================

I've got a hunch this has to do with the introduction of low_s (ie s = N-s if s>N//2 else s) for ECDSA signing, but can't be certain.
Can anyone point out where things are going astray?
Can you post a diff of your branch vs. vbuterin's? – Jimmy Song – 2016-07-26T01:59:40.407
@JimmySong git is not one of my strong suits (and currently using iOS for Python) so it's doable, but can you remind how I do a diff of my HEAD vs vbuterin's master? – Wizard Of Ozzie – 2016-07-27T00:08:34.543
git remote add vbuterin git@github.com:vbuterin/pybitcointools. Thengit fetch vbuterin. Thengit diff vbuterin/master. – Jimmy Song – 2016-07-27T13:57:17.120
