When I look at the History of geopy it seems to be broken because of a wrong MANIFEST.IN which was fixed in master(https://github.com/geopy/geopy/commit/57133938328dc55eeca896ebfbe883cebf860a47). There is also a new tag on github already but not yet on pypi.
I took the package from Source and checked out the 0.96.2 tag. This worked fine for me.
