the previous version to fail: excluded by constraint '>=1.4.0.0' from

[__4] fail (backjumping, conflict set: co-log-polysemy, polysemy,
polysemy-extra, polysemy-methodology-composite)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: polysemy, polysemy-extra,
polysemy-methodology-composite, co-log-polysemy, polysemy-methodology
Try running with --minimize-conflict-set to improve the error message.
