kernel: make gconfig & gtk problem

[gustavo halperin]

Hello List

When I try to make the kernel using the gtk menu (make gconfig) y get the next error:
  make O=/mnt/data2/root/build/kernel-2.6.10/  gconfig
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/basic/split-include
  HOSTCC  scripts/basic/docproc
  GEN    /mnt/data2/root/build/kernel-2.6.10/Makefile
  *
  * Unable to find the GTK+ installation. Please make sure that
  * the GTK+ 2.0 development package is correctly installed...
  * You need gtk+-2.0, glib-2.0 and libglade-2.0.
  *
  make[2]: *** [scripts/kconfig/.tmp_gtkcheck] Error 1
  make[1]: *** [gconfig] Error 2
  make: *** [gconfig] Error 2

but I think that I have all the GTK libraries needed, I have:
 libglade2-0, version: 1:2.5.1-2
 libgtk2.0-dev, version: 2.6.8-1
 libglib2.0-dev, version: 2.6.5-1

So what can be the problem ???

  Thank you,
