How to install mcrypt extension on mac os x yosemite (10.10)

I just installed it right now on my Mavericks installation using homebrew and it worked surprisingly well. Can't say whether or not it will work so well on Yosemite but worth a shot..

Homebrew

brew install autoconf
brew install mcrypt

Macports

Check PHP version
```
php -v
```
Update Macports
```
sudo port -v selfupdate
```
Download & install the appropriate version..
```
sudo port install php55-mcrypt
```
now dummy proof it..
Find where Macports put the file mcrypt.so and copy it to all instances of /php/extensions/no-debug-... folder. If you have that directory structure in multiple places, copy it to all of them. So every php/extensions/no-debug.. folder on your computer has a copy of mcrypt.so
```
sudo cp /opt/local/lib/php/extensions/no-debug-non-zts-20090626/mcrypt.so /usr/lib/php/extensions/no-debug-non-zts-20090626/
```
Determine where your php.ini file is and make sure it's the one your actually using because you may have this file in more than 1 place. Do this to all php.ini files you find..
Within that file find and uncomment the following line. If it's commented out, uncomment it. If it's not in the file at all, add it. In my default php.ini file I found this on line 536:
```
extension=mcrypt.so
```

Compile

Download mcrypt

curl -O http://downloads.sourceforge.net/project/mcrypt/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz

Uncompress it
```
tar -zxvf libmcrypt-2.5.8.tar.gz
```

Configure, build, and install

./configure && make && sudo make install

Download Autoconf

curl -O http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz

Uncompress it
```
tar xvfz autoconf-latest.tar.gz
```

Configure, build, and install

./configure && make && sudo make install

Apache

Regardless which method you used to install it. You should always restart Apache when your done.

Restart Apache
```
sudo apachectl restart
```

Problems with installing mcrypt support for php54 using Homebrew on Mountain Lion

Well, after much trial and error, I solved the issue.

I first had to uninstall php54-mcrypt again to remove the --without-homebrew-php flag and reinstall it with support for the php version installed by homebrew.

$ brew uninstall php54-mcrypt
Uninstalling /usr/local/Cellar/php54-mcrypt/5.4.11...
$ brew install php54-mcrypt
...
==> Summary
  /usr/local/Cellar/php54-mcrypt/5.4.11: 3 files, 56K, built in 33 seconds

Then, I edited my httpd.conf file and changed the location of php. I just commented out the system PHP and added a new line to the LoadModule directives to the PHP installed through Homebrew.

#LoadModule php5_module libexec/apache2/libphp5.so
LoadModule php5_module /usr/local/Cellar/php54/5.4.11/libexec/apache2/libphp5.so

I then installed phpmyadmin through Homebrew with

brew install phpmyadmin

Then I added the following to the bottom of httpd.conf

Alias /phpmyadmin /usr/local/share/phpmyadmin
    <Directory /usr/local/share/phpmyadmin/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        Allow from all
    </Directory>

I made any changes I need to make in the homebrew installed php.ini located at /usr/local/etc/php/5.4/php.ini and modified the configuration file for phpmyadmin located in /usr/local/share/phpmyadmin/config.inc.php.

I then restarted apache using sudo apachectl restart

All is good to go!

NB: Step three below is not required on recent versions of brew:

Third open php.ini file and add reference:

Finally, restart apache:

sudo apachectl restart
