You need to compile PHP with the --with-mcrypt[=DIR] parameter to enable this extension. DIR is the mcrypt install directory. Make sure you compile libmcrypt with the option --disable-posix-threads.

You can install Mcrypt from the PHP Source Tree as a module if you choose.
You first need to ensure you have libmcrypt, libmcrypt-devel, and mcrypt installed, then do:
# cd php-5.x.x/ext/mcrypt
# phpize
# aclocal
# ./configure
# make && make install
Enable the module by adding: 'extension=mcrypt.so' to PHP.ini.
Done!
Very handy if you need to install a single module and you may have installed PHP via RPM, but don't wish to recompile your whole PHP install.
If using a Debian-based Linux system, you can run the following commands:
sudo apt-get install php5-mcrypt
sudo /etc/init.d/apache2 restart
Note, for Ubuntu, simply installing php5-mcrypt did not get mcrypt to work. You need to execute the following commands as root to enable it:
apt-get install php5-mcrypt
mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
php5enmod mcrypt
service apache2 restart
I needed to install mcrypt on Mac OS X Mavericks 10.9 for installing the Laravel 5 framework. I entered in the Terminal command line:
brew tap josegonzalez/homebrew-php
brew install php54 php54-mcrypt
This installed Mcrypt. In Terminal type php -i to see a list of everything installed or for much better formatting and easier to read make a phpinfo.php page with this inside <?php phpinfo(); ?>
More help with installing on OS X:

On Ubuntu 14.04 LTS using php5-fpm with Nginx, I had to symlink the mcrypt.ini to the correct location, and then restart php5-fpm and nginx.#ln -s /etc/php5/mods-available/mcrypt.ini /etc/php5/fpm/conf.d/mcrypt.ini
#service php5-fpm restart
#service nginx restart
If you don't have a /etc/php5/conf.d directory, you can simply only do: php5enmod mcrypt
Should be working fine.
