Build error

[Jean K]

Hi all,

I'm trying to build scikit-image locally, in my git folder, and to just add 
it to my PYTHONPATH.
I checked that all the requirements were met (confirmed by pip install -r 
requirements.txt).
However, when I do 

> python setup.py build_ext -i 

I get an error.
I must be missing something but can't really figure out what...
 
This is the output I get:

Apparently the problem would be coming from a missing file _template.c

On the other hand, 

> easy_install --prefix ~/usr scikit-image 

works. 

Any idea of what is going on?

Thanks,
