Hi, there are instructions on the website:

http://scikit-image.org/docs/dev/install.html#installation-from-source

Alternatively, I've attached a version of the example that drops the
dependency on label2rgb. Another alternative would be for us to update the
docs displayed on the website, but I can't ever remember how to do that. :P

Cheers,
