+******************************************************************************
+The <oping.h> header file could not be found in the usual places. The prefix
+paths searched right now are:
+ $search_path
+
+Please rerun Makefile.PL giving the prefix to the oping library using the
+`OPING_PREFIX' argument. If you, for example, had installed the oping library
+to /tmp/oping, the header file would be at /tmp/oping/include/oping.h; you'd
+then need to run the Makefile.PL as follows:
+ perl Makefile.PL OPING_PREFIX=/tmp/oping
+
+As you can see, the argument passed via `OPING_PREFIX' must be the same
+directory you passed to the liboping configure script using the `--prefix'
+argument.
+
+No Makefile has been created.
