******************************************************************************
* ERROR: COULD NOT FIND THE NEEDED HEADER FILE <oping.h>!                    *
******************************************************************************
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.
