How do I invoke a CGI script from a PmWiki recipe?

Try this, in the example the script being executed is tuesday.pl.

<?php if (!defined('PmWiki')) exit();
#
# This recipe illustrates calling a CGI program from a PmWiki recipe.
# Version date
$RecipeInfo['RunCGI']['Version'] = '2012-09-08';
$FmtPV['$RunCGI'] = $RecipeInfo['RunCGI']['Version']; // return version as a custom page variable
# 2012-09-05 Initial version

# declare $RunCGI for (:if enabled RunCGI:) recipe installation check
global $RunCGI; $RunCGI = 1;

Markup('RunCGI', 'fulltext', '/\\(:runcgi:\\)/ei',
  "Keep(RunCGI())");
function RunCGI() {
  $retval = 'retval is ';  
  $lastline = '';
  $output = '';
  $lastline = exec("../cgi-bin/tuesday.pl", $output); // return result of executing file
  $retval .= ' exec:' . pre_r($output);
  $retval .= ' fgc:' . pre_r(file_get_contents('../cgi-bin/tuesday.pl')); // return contents of file

  return $retval;
}
