Compiling gtk error - png ???

[Jose Marcio Martins da Cruz <Jose-Marcio Martins ensmp fr>]

Hello again,

When I try to compile gtk+-2.2.1, I have the following error
message :

gmake[3]: Entering directory

I'm using the following command to configure gtk :

#! /bin/sh

PREFIX=/usr/local/gtk-2.2.1
export PREFIX

PKG_CONFIG_PATH="$PREFIX/lib/pkgconfig:/usr/local/lib/pkgconfig"
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

./configure \
        --enable-static=yes \
        --enable-shared=no \
        --prefix=$PREFIX \
        --disable-gtk-doc \
        --disable-modules \
        --with-x
 
libpng is correctly (I think) installed.

Maybe someone have an idea...

Thanks
