Parag Nemade (1):
      Add some code compatibility for python3. It is seen that on Fedora Caribou rpm build failed for 
python3. If used 2to3 tool everything works fine, but if I remove it then build fails. I tried to find 
minimal changes required in code compared to what 2to3 tool is offering changes. With this attached patch 
build on Fedora for python3 succeeds.
