Configuration problems (--with-zlib ??)

Hello!

I am having some trouble configuring php for installation on my FC3 system.

I am trying to install php-4.4.0 with the following options:

./configure --prefix=/usr/local/php ppwith-apxs2=/usr/sbin/apxs
--with-mysql=/usr/local/mysql

However, I keep running into this error:

configure: error: Try adding --with-zlib-dir=<DIR>. Please check
config.log for more information.

Well, zlib is actually installed on my system, and even when I set the
value of the dir, I just get more errors:

--with-zlib-dir=/usr/lib (where libz.so.1 is located)

configure: error: Cannot find libz.


Any ideas of what I'm doing wrong?


Thanks!
