configure: error: mcrypt.h not found. Please reinstall libmcrypt.

解决办法:

wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/attic/libmcrypt/libmcrypt-2.5.7.tar.gz 
tar -zxvf libmcrypt-2.5.7.tar.gz 

cd libmcrypt-2.5.7 

./configure

make

make install

因为centos6.x 默认的yum源没有libmcrypt-devel 这个包，只能借助第三方yum源。
