Gang, I've rebased the patches for our Spark package atop the first prerelease for 0.9.1. This version will be the default in rawhide as soon as the non-scratch build finishes, so if you experience trouble, please let me know.
The latest package also includes the upstream-parity fixes in the previous one I cut: mesos and stream-lib are now compiled in since they are available now.
best,
wb
