[MonoDevelop] Bad version of Glade

[Arnoux Vincent]

Hello the List,
I am running Monodevelop 0.5 on a Mandrake 10.0. I had a hard time to 
make it compile, but now it's OK.
However, I still have a little "strange" thing: when I double-click 
ressource and gui.glade, Glade is opened but I have a message saying 
"Error - Non valid entity".
Actually, Glade 0.6.4 is opened instead of Glade 2.5.1. If I open myself 
Glade 2.5.1 and modify gui.glade, everything is OK.
So, anybody know how to have monodevelop open Glade 2.5.1 instead of the 
old version ?

Regards,
Vincent
