Recompile php

Before you configure the php sourcecode you must remember the previous php configuration right ? if not you can use php -i |grep configure to see the previous configuration

./configure --with-apxs2=/usr/local/apache2/bin/apxs \
> --with-mysql=/usr/local/mysql \
> '--with-gd=/usr/local \
> --with-jpeg-dir=/usr/local/lib \
> --with-zlib-dir=/usr/local \
> --enable-ftp \
> --with-png-dir=/usr/local/lib \
> --with-freetype-dir=/usr/local \
> --with-curl=/usr/local \
> --with-imap=/usr/local/imap-2007b \
> --with-imap-ssl=/usr/local/ssl \
> --enable-mbstring \
> --with-mcrypt=/usr/local/bin/mcrypt
# make && make instal
# vi /usr/local/lib/php.ini
; change this line
include_path = ".::/usr/local/lib/php"

cek

# php -i |grep ^mcrypt
mcrypt
