This should work unless some restrictions are set on that PHP installation.  
You may also try simply

  file_get_contents('http://ttc.org.nz/cgi-bin/tuesday.pl');

This would probably never work. You normally cannot execute remote files.

Same here.

>   $lastline = exec("./cgi-bin/tuesday.pl", $output);

This will likely be "../cgi-bin/tuesday.pl" with 2 dots, because it looks  
like your running pmwiki.php file is in a directory pmwiki, while the cgi- 
bin directory looks like it is in the document root, and not inside the  
pmwiki directory.

For testing purposes, in order to see the array values rather than 'Array',  
try

   return pre_r($retval);
