problem installing openssh

[Ancelmo Rodriguez Parra]

I am still trying to install openssh, I did like Kevin told me but it
didn't work, I tried it like this:

VER=openssh-2.3.0p1
SRC=/usr/src

CFLAGS="+w1 +W 486,474 +O3 +ESlit +Optrs_strongly_typed \
> -I/opt/zlib/include/"
LDFLAGS="-L/opt/zlib/lib/"

# ./configure --prefix=/opt/${VER} \
> --sysconfdir=/etc/opt/openssh \
> --with-default-path="/usr/bin:/usr/sbin:/opt/${VER}/bin" \
> --with-ssl-dir=/opt/openssl/lib/ \
> --disable-suid-ssh \
> --without-pam

However, I got the following error:
checking for deflate in -lz... no
configure: error: *** zlib missing - please install first ***

I have already instaled zlib:
# ls /opt/zlib/lib
libz.a   libz.sl

and openssl, any help?
