Strange bad installation of Pango causes no text in all gtk-widget

[Philemotte Christophe <cphilemo iridia ulb ac be>]

Hello,

I have upgraded my gtk to gtk2 2.2.1-4

thus I have upgraded also Pango to 1.2.1-3
and my XFree86


apparently, i have a problem with my pango installation, when i run 
gnome, i have this error for all gtk application (and gnome desktop, 
nautilus, applet)

---
WARNING **: No builtin or dynamically loaded modules
were found. Pango will not work correctly. This probably means
there was an error in the creation of:
  '/usr/local/etc/pango/pango.modules'
You may be able to recreate this file by running pango-querymodules.

i have verified this file , and all it is ok, i have verified the 
linking of libpangoxft-1.0.so and all seems to be ok
