How do I fix this?
We are using a newer version of libgit2 than the standard release
(libgit2.0.25.0 instead of libgit2.0.24.0 - some hard dependency in
our code).
However, after I install libgit2 (25), I get this error chain:
pip install pygit2
Collecting pygit2
Using cached pygit2-0.25.1.tar.gz
Complete output from command python setup.py egg_info:

Exception: Version mismatch: this is the 'cffi' package version
1.10.0, located in '/usr/lib64/python2.7/site-packages/cffi/api.pyc'.
When we import the top-level '_cffi_backend' extension module, we get
version 1.9.1, located in
'/tmp/pip-build-OX9KGK/pygit2/.eggs/cffi-1.9.1-py2.7-linux-x86_64.egg/_cffi_backend.so'.
The two versions should be equal; check your installation.
