Dear Chris - I have added igraph.get_include() in the following commit:
https://github.com/igraph/python-igraph/commit/e50191d6f96b48b2885f425b8c725f0768443245 This will probably make it into python-igraph 0.7.1.post7, 0.7.2 or 0.8, whichever will come first. Let me know if it's urgent for you to get this in an official release -- in that case, I can probably push out 0.7.1.post7 next week.
