Searching the internet, I have found reports of other applications which depend on libz.so, one of these reports suggested copying the link "/user/lib/libz.so.1" and renaming the copied link to "/user/lib/libz.so".
I did this and then the "System Profiler and Benchmark" program was able to save the report without error. I suggest that for backward compatibility not only the link "/user/lib/libz.so.1" should exist but also a link "/user/lib/libz.so", if not then all programs (eg "System Profiler and Benchmark") which reference "/user/lib/libz.so" should be modified to reference "/user/lib/libz.so.1"
