Given that this code is only ever executed, if `OMP_DEBUG` is enabled, it would be more useful to tell the user what to do in this case: "The OpenMP runtime could not determine the location of libompd.so. If the debugger fails to load the library, make sure to add the directory containing a compatible libompd.so to your LD_LIBRARY_PATH"
