failed to build version 0.12

[Jens Nielsen]

Sorry but I am also seeing this happening with Cython 0.23.4 so I doubt 
that the Cython version is the problem. 

(test) ✔ ~ pip list
cycler (0.10.0)
Cython (0.23.4)
dask (0.8.0)
decorator (4.0.9)
matplotlib (1.5.1)
networkx (1.11)
numpy (1.10.4)
Pillow (3.1.1)
pip (8.1.0)
pyparsing (2.1.0)
python-dateutil (2.5.0)
pytz (2015.7)
scipy (0.17.0)
setuptools (20.2.2)
six (1.10.0)
toolz (0.7.4)
wheel (0.29.0)
(test) ✔ ~ pip install scikit-image

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in 
/private/var/folders/zz/yg37r3x91_d5kkj0k8x8g0cm0000gn/T/pip-build-rqta5vux/scikit-image/

The problem is that skimage/morphology/setup.py contains:

cython(['_skeletonize_3d_cy.pyx.in'], working_path=base_path)

but that file is not in the pypi tar ball. It should presumably try to 
process the template processed file _skeletonize_3d_cy.pyx?
