php install zlib error

I am trying to compile php and I get the following error:

configure: error: Cannot find libz
#

I have tried a couple of different commands like:
CFLAGS=3D'-DEAPT' ./configure --with-apxs2=3D/usr/local/apache2/bin/apxs
--with-mysql=3D/opt/sfw/mysql --with-zlib=3D/var/tmp/zlib-1.2.1
--with-gd=3D/opt/sfw/include

I have apache and mysql working currently.

Any help would be appreciated.

Thanks

Download the zlib development package. zlib-devel-1.2.2.2-1.i386.html

I rely on Yellowdog Package Manager (yum) to install the libraries I need. T
o know the name of the development version, use rpmfind.net to see if the de
velopment version exists. I've had this happen before where I was downloadin
g libstdc or some other standard library, and I found out the problem was th
at I didn't have the development package of that library. Same goes for this
, the command "yum install zlib-devel" installed the package, and then PHP g
ot past the zlib....

....instead it got stuck on Curl 

I actually got through the Curl problem, and more. If you have any other han
gups, I think I've figured out how to get the development libraries installe
d, even if you have to do it via the right order RPM packages which are depe
ndent on each other.
