Use double-quotes in the include_once() line, as in:

    include_once("$FarmD/Cookbook/XToDo.php");

With single quotes, PHP is looking literally for a directory
named '$FarmD' (i.e., dollar-sign + 'FarmD'), and it isn't finding one.

$FarmD is a PHP global variable, but it's not a page variable
(i.e., one that can be accessed via markup).  For a variety of
reasons (including security), PmWiki restricts the {$...} markup
to certain variables (defined by the $FmtPV array).
