My configure line used to work on a redhat 6.2 system.
Now I have upgraded, it does not work any more, it seems not to find any function in the mcrypt library...

configure line:
----------
./configure	--with-mysql \
		--enable-track-vars \
		--with-apache=../../../apache/make/apache_1.3.19 \
		--prefix=/home/local/php \
		--with-config-file-path=/home/local/php/conf \
		--without-gd \
		--disable-debug \
		--with-mhash=/home/local/mhash-0.8.9 \
		--with-mcrypt=mcrypt-2.4.10 \
		--with-mm=/home/local/mm \
		--enable-trans-sid \
		--with-dom= \
		--with-magic-quotes \
		--with-zlib-dir=/home/local/zlib \
		--with-imap=/home/local/libimap

configure output:
