The #PyYAML problem is only getting better. People are trying really hard to make their things work again. Apparently there's a way to force constraints on pip but it's not a perfect solution either.

I have two thoughts about this:

1. *Finally*, it's not just us in #Gentoo being hit by constraint conflicts (i.e. two packages in depgraph requiring different #Cython versions).

2. Given that PyYAML knew about the problem for a year and a half and did nothing to avoid it… do you think it's a good idea to continue using that package? Or #YAML in particular, Norway?
