setuptools (it's used as a package locator but importlib.metadata in
newer Python core or the external importlib_metadata are preferred).
So drop the RDEP in that case (it's still kept for py27) and bump
revisions.
Doing "import sklearn" resulted in breakage at runtime due to sklearn
0.20.3 not being compatible with python 3.8.
In addition:
- add WANTLIB
- rework the DEPs for the new version
- remove SKLEARN_NO_OPENMP which was dropped in commit 9876f748
Breakage initially reported by James Cook (who provided many pointers on
moving forward) and also tested the update.
scikit-learn is a BSD-licensed Python module for machine learning
and data mining built on top of SciPy.
Initially created by robert@, modified by me and kmos@.
This is not polished enough, but it can improved in the tree now.
Once the 21 branch rolls out a new version, we will probably update to that.
Currently it is broken for non-OpenMP builds.
OK robert@, kmos@
