Runtime failures delivered by multiple package managers #558
Description
Hello,
I was using Pygit2 as packaged by MacPorts successfully a week or three ago. I've been keeping my MacPorts tree up to date regularly. Today, I tried using Pygit2 again (port py34-pygit2), and I received an asynchronous error. The traceback started after I receive the prompt for the next command.

This issue looks similar to the build failure currently being experienced in the next Ubuntu's nightly builds. According to the Launchpad issue tracker, the upstream Debian issue has not been resolved yet.
It looks like this is related to a cffi update, according to Issue 534.
So it's clear: Pygit2 currently fails as packaged by three operating systems using two package management systems. It looks like at least one additional file needs to be built during the build scripts, but I'm not sure if that's the correct solution or a hack.
