The mail was from Selva. If you checkout 0.5 branch and build it, you are not really getting the real 0.5 release. You can get the release source code for 0.5 release from: http://people.apache.org/~sneethir/ranger/ranger-0.5.0-rc3/ranger-0.5.0.tar.gz Please try building from that source and confirm if you still see the problem. I think you would not see the problem with that source.
