How to install mcrypt on PHP 5.4?

alkarim: I never bothered checking phpinfo, I always go to php.ini and uncomment an extension, the problem with mcrypt is that it is not in php.ini, but when I checked phpinfo it is there.

Do the one thing you think you cannot do. Fail at it. Try again. Do better the second time. The only people who never tumble are those who never mount the high wire.
