Sphinx for documentation is missing in environment

[shaker6691]

It would be nice to have sphinx preinstalled. This is sufficient for compiling the documentation.

A not-too-old version of the compiled developer documentation for the primary repos can be found in the following places.

http://ilastik.github.io/ilastik
http://ilastik.github.io/lazyflow
http://ilastik.github.io/volumina

To install sphinx into the Linux binary environment, use conda's -p option:

conda install -p /path/to/ilastik-1.2.0rc10-Linux sphinx
