ah! so this was what was happening, thanks for finding that out :)

it looks like it's been changed in fping 4.x (parsing output of a
human-formatted command will invariable lead to this kind of result, but
I can't think of a better method for now :\ )

we probably want to keep the check working with 3.x, just like I had to
fix for the -4/-6 options, since there still are distributions that ship
fping 3.x. So the line would probably look like this in order to match
both cases:

    $self->{enable}{S} = (`$binary -h 2>&1` =~ /\s-S,?\s/);

would you like to submit this as a pull request? (you can also do that
on github by modifying the line directly on the web interface)
otherwise, if you prefer I can submit it and I'll make sure to credit
you as the one who figured this out.

Cheers!
