Thx

for the record: what's the best way of building the docs locally to match the html in the scipy.org? Doing make html or python setup.py build_sphinx I only managed to produce an older-looking htmls with weird errors here and there.

I'm using

python runtests.py -g --shell
make -C doc html

or

make -C doc dist

python setup.py build_sphinx should in principle also work :(

If you have Numpy installed as setuptools egg, then that may also cause problems, since eggs override PYTHONPATH environment variable... Perhaps python setupegg.py build_sphinx does work.
