uncaught exception

[jscar]

Hi there
this worked great with a number of extensions but when I came to look at MageMonkey I got this:

$ php meff.php Ebizmarts_MageMonkey
PHP Fatal error: Uncaught exception 'InvalidArgumentException' with message 'RegexIterator::__construct(): Unknown modifier 'l'' in /chroot/home/XXXX/html/shell/meff/FileIterator.php:53
