what is missing (windowmaker solaris9)

[Riccardo Mottola]

Hi,

I'm trying to rebuild windowmaker against the new libpng.
On solaris 9, configure fails (on sol10 it succeeds):

checking for fontconfig library... sh: gnome-config: not found
Package fontconfig was not found in the pkg-config search path.
Perhaps you should add the directory containing `fontconfig.pc'
to the PKG_CONFIG_PATH environment variable
No package 'fontconfig' found
not found
checking for the Xft2 library... sh: gnome-config: not found
Package fontconfig was not found in the pkg-config search path.
Perhaps you should add the directory containing `fontconfig.pc'
to the PKG_CONFIG_PATH environment variable
Package 'fontconfig', required by 'Xft', not found
sh: gnome-config: not found
Package fontconfig was not found in the pkg-config search path.
Perhaps you should add the directory containing `fontconfig.pc'
to the PKG_CONFIG_PATH environment variable
Package 'fontconfig', required by 'Xft', not found
found
checking whether libXft is at least version 2.1.0... no

ERROR!!! libXft on this system is an old version.
          Please consider upgrading to at least version 2.1.0.

gmake[1]: *** 
[configure-work/build-isa-sparcv8/WindowMaker-0.95.5/configure] Error 1

CSWfconfig  is installed.

    PKGINST:  CSWfconfig
       NAME:  fontconfig - A library for configuring and customizing 
font access.
   CATEGORY:  application
       ARCH:  sparc
    VERSION:  2.8.0,REV=2012.05.20

which is > 2.1.0

What could be the problem, a dependency not listed? what is gnome-cfg? 
something like pkg-config?
