/usr/bin/ld: cannot find -lz error

I am installing lxml module for python on redhat
I have installed libxml2 already.
When I run for libxslt:

./configure --prefix=libxslt_folder --with-libxml-prefix=libxml2_folder

It is ok
the I run :

make

I have error:

/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status

I found in google that is connected somehow with static library, but I still cannot find how to solve it.

It seems, you need the "zlib compression and decompression library".

yum install zlib

zlib.i386 and zlib.x86_64 are already installed

There should be a

/lib/libz.sl*

file which is a symlink to the real

libz.sl.whatever

You may need zlib-devel or its redhat equivalent.
