In tutorials/proof/getProof.C
     - Use default port 40000 (80000 is above the max allowed on some machines)
     - Use "xpdtut" instead of "xpd-tutorial" to shorten the paths
     - On MacOsX, create unix sockets under /tmp/xpd-sock
   In test/stressProof.cxx
     - Use "xpdtut" instead of "xpd-tutorial" to adapt to the change in getProof.C
     - On MacOsX do not add the username in the tep sub-directory
     - Add missing protection when printing the run statistics (gProof must be defined)
