问题
I'm using CentOS 6 and the latest phpMyAdmin (4.0.1.4) and I noticed the error "The mcrypt extension is missing. Please check your PHP configuration."
I went ahead and ran:
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
then ran:
yum install php-mycrypt
Then restarted httpd services and still no luck.
Any idea how I can get it to go away?

According to this post, you should edit /etc/php.d/mcrypt.ini and change
; Enable mcrypt extension module
extension=module.so
to
; Enable mcrypt extension module
extension=mcrypt.so
and then restart.

On Ubuntu Try this for your mcrypt problem:
mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
sudo php5enmod mcrypt
sudo service apache2 restart

I know you asked for CentOS 6, but in case someone happens to have the same problem for OSX lion/mountain lion, here is a solution
Basically they make you (re)install libmcrypt and the latest version of php, and if you don't have it, autoconf.
Just follow the tutorial, it should work flawlessly.

In CentOS, Yum did not work for me. I downloaded and installed libmcrypt-*.tar.gz. See similar instruction in this link. http://www.php.net/manual/en/mcrypt.installation.php.

Mac OS X Yosemite
the requested PHP extension mcrypt is missing from your system
I fixed this error by running the following commands in my Terminal :
brew update
brew upgrade
brew tap homebrew/dupes
brew tap josegonzalez/homebrew-php
brew install php54-mcrypt
