This definitely is a problem of linking against a different shared library multilib than the one used at runtime. The libxerces-c1_6_0.a library appears to have been built and linked with -pthread option, but superman may not have been built that way. -pthread uses .../lib/pthread/libstdc++.a, for wherever GCC was installed. .../lib/pthread/libstdc++.a has pthread_mutex_t symbols, .../lib/libstdc++.a does not. AIX does not have weak bindings of pthread functions for non-pthread applications. One has to use -pthread consistently. Either superman was compiled and linked differently, so the built-in runtime LIBPATH is wrong, or the LIBPATH environment variable explicitly is set and overriding the application LIBPATH to point to the default shared library installation directory instead of the one appropriate for the application.
