[gradsusr] problem while installing the libpng after zlib

[muhammad hasan ali baig]

Hi dear fellows,
                     I am using the GrADS version 2.0.a9 and I wish to
install supplemental libraries from
http://iges.org/grads/gadoc/supplibs.html. I followed each and every step as
mentioned there.
My laptop system supports i686 i686 i386 GNU/Linux. I want to convert my
data into GRIB2 format by using GrADS. For this purpose, i want to use
g2clib 1.1.8. Before installing it, it is necessary to install some other
libs like zlib and libpng. I successfully installed the zlib but when i
tried to install libpng following eror message occurred:

  checking for zlibVersion in -lz... no

configure: error: zlib not installed

While i had already installed zlib as shown from the following messages:

Could you guide me how to resolve this problem?
