Research direction

Start by reproducing sudo pip install git-deps in the reported macOS Python 2.7 environment and inspect the pygit2 build requirements around the missing git2.h header. Trace whether the project documents or controls this dependency; done means the installation succeeds or the required prerequisites and failure are clearly documented.

Description

maybe this is not a git-explode issue, but still I've run into it:

sudo pip install git-deps

results in:
