Python3 + PyYaml conflict

[mixmastamyk]

Hi,

I have a python3 kivy project and found a yaml recipe at github. But when it is added to my requirements line in the .spec file, it complains that it is forcing python2 because of it depending on setuptools.

I'm guessing setuptools can be removed on python3?

This happens because the setuptools recipe has only python2 as a requirement. As far as I remember, there's no need for this and it would be fine to add python3crystax as an alternative. If you could check that this works, a PR to fix it would be welcome.

Changed to this:

depends = [ ('python2', 'python3crystax') ]

Received this:

Some of the earlier log output should describe which recipes are being required and why.

Closing as the pyyaml recipe was replaced.
