I upgraded to Sphinx 1.6.4 and also removed the numpy_ext/ and sphinx_gallery/ directories in doc/sphinxext/. Build is running successfully now. I think we should delete these folders too in make clean. What do you think @jnothman ?

Glad you got it working, closing. doc/sphinxext/numpy_ext and doc/sphinxext/sphinx_gallery folders don’t exist in master any more so there is no point deleting them in make clean.

The problem @lesteve is that if there are files left in those directories, git won’t remove them upon checkout. They can then interfere with doc building.

We’ve previously cleaned up reminded directories in sklearn for this reason. Could do same for doc. To be safe could only remove pyc and similar files.
