Fix package permission for Linux binaries
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
We don't have a consistent permissions setup for our linux binaries. Some libraries are user-accessible only, while others are world-readonly-accessible etc. We need to adopt a consistent model. My vote would be user-r/w/(x), group-r//(x), world-r//(x).
The discrepancies exist beyond ParaView libraries e.g. generic io, matplotlib, numpy etc. All these packages will need to be fixed.
