+    Cast time_elapsed to int before calling human_readable_duration
+    
+    When attempting to build againt EPEL 5, it was noticed that
+    human_readable_duration expects an int, but time_elapsed is an
+    integer.  Explicitly static_cast<int>( time_elapsed ) to appease older
+    compilers.
