Um, phpprogrammer, easyphp isn't the cure for world hunger, you know...
chrissanz: you also need to configure PHP properly: PHP doesn't use libmcrypt directly - it's not a PHP extension. If you read the extension list in php.ini you'll've read the line:
;extension=php_mcrypt.dll
and you'll need to uncomment that. php_mcrypt.dll is a PHP extension, (it should be in PHP's extensions directory) and it links to libmcrypt.dll.
Plus, you'll need to fix up all the changes you've done to your installation of libmcrypt trying to get this to work 🙂
[edit: I just noticed that I basically repeated the notes from the emini site; but what you describe doing is nothing like what was written there.]
