I'm also working on a scikit-learn recipe, you need to create a recipe to provide python3-scipy-native as it uses this during the build process. However, even with this recipe in place and scikit-learn building, the resulting packages doesn't work due to inconsistencies in the build, with the most obvious failure looking like a 64bit -> 32bit compile error from using the native include headers in cython generated files. I'm still looking into this but if anybody else has managed to get this compiled properly I would also be interested in hearing about it.
