GTK+ 1.2.10 and 2.0 installed !!!

Sorry for my poor english (i'm french)

I've just upgraded my Mandrake 8.2 to 9.0.
When I want to install a RPM archive (D4X) an error message tell me that
I've the wrong version of GTK (1.2.10) instead of the 2.0.6.
But the 2.0.6 is installed on my system... and the 1.2.10 too !!!

How can my system recognize the v2.0.6 version ?

Gnome 2 runs whith no errors !! 

Thanx !
